00:00:00I'm doing it.

00:00:02I'm doing it.

00:00:24What are you doing?

00:00:26What have you done today?

00:00:30Let me write.

00:00:34Just write.

00:00:36Let me write.

00:00:38Wave Optics.

00:00:40It's an easy chapter.

00:00:42It's 7-7 lectures.

00:00:46It's ready to prepare.

00:00:48It's ready to prepare.

00:00:50It's ready to prepare.

00:00:52It's ready to maintain.

00:00:54It's going to be 4 days.

00:00:58It will be 4 days.

00:01:004 days in your chapter.

00:01:02It's 7 days.

00:01:04It's 7 days.

00:01:06And it's 4 days.

00:01:08It's 4 days.

00:01:10So, you should do a particular thing that, Sir, in four days, I will do a bigger thing.

00:01:14No one will do it.

00:01:16Okay, let's go.

00:01:18Interference.

00:01:19Now, close the line and close the line.

00:01:27Two sources are S1 and S2.

00:01:35This source is light and sound.

00:01:41If there are sound sources, then they will be speaker.

00:01:45If there are light sources, then they will be bulb.

00:01:48And point P, S1 and S2, and S2.

00:02:01If there are light sources, then they will be bulb.

00:02:09So, point P, people are superimposed.

00:02:14What is the superimposition?

00:02:16What we call it is that, don't notice wave of the resultant, i.e.

00:02:22Super position.

00:02:24And, if we call it superimposed, then it will be the place to be the resultant.

00:06:33is 5 meter so part difference Bada Rasta minus Chota Rasta

00:06:46the part difference Bada Rasta minus Chota Rasta

00:06:49like this

00:06:59and see

00:07:01feel

00:07:06not the question

00:07:07this is the question

00:07:08this is the question

00:07:11this is the Slit

00:07:12We will go ahead and study our main topic, YDSC, Young Double Slitter Experiment.

00:07:19We will go ahead and study our main topic.

00:07:46In fact, Polarization was one of the main topic.

00:07:50How many problems were there?

00:07:53So, there is no big problem.

00:07:55There is a good thing to do.

00:07:59Now, let's see.

00:08:01There are two S1 and S2.

00:08:03Let's take a look.

00:08:05Now, let's tell yourself.

00:08:07The wave from S1 came to the center.

00:08:11The wave from S2 came to the center.

00:08:14Tell yourself, who's the big road?

00:08:18The two roads are similar.

00:08:20This means my children, my brother.

00:08:24Part difference is zero.

00:08:26Part difference is what is?

00:08:30What is what?

00:08:31in the very small example when you get the train,

00:08:33You get to know what is this way.

00:08:34The S2 is 10 meters.

00:08:36The S3 is 15 meters.

00:08:38And the path difference is 5 meters.

00:08:42It is absolutely basic.

00:08:44These all are coming.

00:08:46and then we have a basic understanding, path difference, path difference.

00:08:52Let's go.

00:08:56Let's write a little bit.

00:08:59Third example.

00:09:05This is a circular screen.

00:09:12This is a circular screen.

00:09:17Here are two swords.

00:09:19S1 and S2.

00:09:22This is a 2 lambda.

00:09:26This is 4 points.

00:09:28Look, we are looking at it.

00:09:30We are looking at it.

00:09:32We are looking at it.

00:09:34We are looking at it.

00:09:36You can write it.

00:09:38Two swords.

00:09:40Which is a 2 lambda?

00:09:42Now, you have asked.

00:09:44In 4 points,

00:09:45Phase difference,

00:09:46Part difference.

00:09:48.

00:10:00.

00:10:11अब सीख का थोड़ा सा सवाल को कठिन किया है है नLoji ईए रहेगा सवाल बदलते रहेंगे भाई

00:10:24लॉजीक ऌई रहेगा लॉजीक एक ही है रामचला 10 श्यामचलाअ 15 पाथडिवरेंस पांच

00:10:33and now look at the board, now look at the board, you can understand all of the people,

00:10:40it's fun to see the point 2, S1 from the wave reached, S2 from the wave reached,

00:10:46tell yourself, who is the same road, the same road, the same road, the same road,

00:10:51so part difference is zero, here see, both the same road, part difference is zero,

00:11:01now look at the board, come on to 1, tell it's fun, the color will change,

00:11:08from the wave to the wave, this one will go, this one will go,

00:11:14from the wave, this one will go, from the wave to the wave,

00:11:18it's easier to explain them, who is the same road?

00:11:24s1, s1, s1, s1, and tell us, here, the two two directions are together, means s1, s1,

00:11:32and how much goes, so, so, this one is together, this one is together, this one is together,

00:11:38this one means, here, part difference, two lambda, feel better, think, sir, one more

00:11:47way, this one is together, underscore, here, see, s1, s1, s2, s2, s2, now Kent, tell us,

00:11:59the lower path is Grande path is

00:12:09mental pachel kyaar kiska rasta jada kiska rasta kam to mujhe part difference ki ek bar basic

00:12:19feel aja part difference ka symbol delta x iski ekdom basic feeling aani chahiye iski unit

00:12:27kya hoti hai khu suchu meter hooghi kya ki lembahi toh hai das meter barometer

00:12:38a palitator ekdom clear kisar part difference meri dhimag mein aapne ekdom set kiya

00:12:44chute chute tine example ki sahitah se kya batahi kya bat ok hai aage bada hai jaldi

00:12:52yao fata fata ho hai jaldi yao aagli handa liye phase difference

00:12:59a look nai jaiye baitas jaldi lik lik nai ke baad 2 minit sa da nahi mili ruk jaiye se kam

00:13:03ni chalega fast lik thoda hai oska sabse achha tariqa hai jab mein board pere lik raho

00:13:09tab likta ja jab samjhau tab old girl le aaglab lik hai hai face difference

00:13:22abhi face difference kya hotta dhek isko bhi ekdom takdha feel kar jiasse part difference

00:13:27sikha na waisa hi face difference sikha na waisa hi face difference sikha

00:13:28abh jada sunna

00:13:31kya satsat bana dho wave hai

00:13:34kya yiye pahli wave

00:13:35yiye wave one yiye wave two

00:13:50a

00:13:52a

00:13:53a

00:13:54a

00:13:56a

00:13:57a

00:13:58a

00:13:59a

00:14:00a

00:14:01a

00:14:02a

00:14:03a

00:14:15a

00:14:16a

00:14:17Which time this is zero, this also is zero. Which time this is minimum, this also is minimum. Which time this is zero, this is exactly the same.

00:14:33Two is zero, one is max, one is zero, one is min. This means that two are exactly the same. Both are in the same phase.

00:14:49It means that in their behind phase difference is zero.

00:14:57Sir, tell us a little bit about feeling, how the phase difference is.

00:15:05Now you can see, it's a little systematic, it's good, it's always good.

00:15:09I can see my two hands. Both are zero.

00:15:15One is max, one is zero, one is minus.

00:15:21You will say that both hands are oscillating, but both are in the same phase.

00:15:29Sir, we'll always go on. No, no, no.

00:15:31This could be possible. This could be possible.

00:15:33This could be possible.

00:15:35This could be possible.

00:15:36This could be possible.

00:15:38This could be possible.

00:15:39One is maximum and one is zero.

00:15:40When this is going down, this is going up.

00:15:42This could be possible.

00:15:44Now the moment of time, there is nothing exactly

00:15:45This is weak idea.

00:15:46There, too.

00:15:49There, there.

00:15:51In the same phase, check out.

00:15:52Look at this phase.

00:15:53One is zero and website maximum.

00:15:56One is zero.

00:15:57One is시고.

00:15:58One is komt, a.

00:15:59The meaning of the same phase.

00:16:01You can find that.

00:16:02In the same phase,

00:16:03In the same phase,

00:16:04Let's see the difference.

00:16:05How much time will happen?

00:16:06Two is the same phase.

00:16:07Look at the same phase.

00:16:08One is paling later,

00:16:08One is toplam or chamруam.

00:16:11Sir, one more example, it will be more clear. Let's see. Let's do it. Let's do it.

00:16:21Let's do it.

00:16:26If you learn terms, what do you feel about physics?

00:16:30Okay, this way you have to think about it.

00:16:33It will come to mind you to ask yourself questions or questions.

00:16:41No sir, you have also said this.

00:16:45Seven lectures.

00:16:47You have also told me that there will be four lectures.

00:16:50If I read two or five hours, then the topic will be prepared.

00:16:57So you play the scientific number of lectures.

00:17:01How long, how long, how long, how long, how long, how long, how long, how long.

00:17:05You will show the whole road map.

00:17:07Now, you have seen the physics in the right thing.

00:17:10That, Sir, there is modern running.

00:17:11There is a modern semiconductor.

00:17:13If you start this after you start the electro-dynamics,

00:17:16then the bar will get down.

00:17:17Then the mechanics will be running.

00:17:19There is a systematic.

00:17:21You will see the whole physics plan.

00:17:24You will see the first and two months.

00:17:26Then we will update.

00:17:27So, will the clarity be seen as well?

00:17:29Yes, sir, this sort of syllabus will be completed.

00:17:32This will be done.

00:17:33How will I tell you?

00:17:35How will I tell you how to tell you?

00:17:37How will I tell you?

00:17:38How will I tell you?

00:17:40How will I tell you?

00:17:41Now, the board will see.

00:17:42This will look at.

00:17:43Now, what will this feeling?

00:17:44What will happen to you?

00:17:45Both were starting from zero.

00:17:49They were starting from one school.

00:17:52But the number of brothers had increased.

00:17:55Positive.

00:17:57One brother was going in the car.

00:17:59Look at that.

00:18:00The brother got hit.

00:18:02The brother got hit.

00:18:03The brother got hit.

00:18:05Both are here.

00:18:06Both are in the same place.

00:18:07In every city.

00:18:08You depend on your own.

00:18:10What you are taking positivity,

00:18:12which you are grabbing.

00:18:14You are improving.

00:18:15You can see.

00:18:16What is happening?

00:18:17Both were 0.

00:18:19This is going to be further.

00:18:22This is going to be further.

00:18:23This is going to be further.

00:18:24Now, how much is the phase difference?

00:18:25180.

00:18:26Both are in opposite phase.

00:18:29This is the maximum.

00:18:32This is the maximum.

00:18:34This is the minimum.

00:18:35Then, this is the minimum.

00:18:37This is the minimum.

00:18:39We say both are in opposite phase.

00:18:43Opposite phase.

00:18:44Opposite phase.

00:18:45Opposite phase.

00:18:46Opposite phase.

00:18:47And what difference is in their face?

00:18:49180.

00:18:50Like the biggest example.

00:18:52Mom and Dad.

00:18:53Best example.

00:18:54You can see them.

00:18:55You can see them.

00:18:56You can see them.

00:18:57Thomas and Dad.

00:18:58You can see them.

00:18:59You can see them.

00:19:00So interesting.

00:19:01You know.

00:19:02As a kid,

00:19:04political part changes.

00:19:05No matter how difficult.

00:19:06You can pick up.

00:19:07Here.

00:19:08He has on opposite.

00:19:09He is in opposite place.

00:19:10He has on opposite side.

00:19:11He is in opposite side.

00:19:12He is in opposite side.

00:19:13He is in opposite side.

00:19:14He is in opposite side.

00:19:15school and father-in-law has become angry from here from here from here from here from here

00:19:19father-in-law and mother-in-law

00:19:22father-in-law

00:19:26father-in-law said no, 25 years ago, I have to get you with me

00:19:29brother-in-law, father-in-law has become angry from here

00:19:32and you take it there, it's fun

00:19:35so both are in opposite face

00:19:38opposite face, between both face difference, how many degree?

00:19:41hexosuric, so delta phi, delta phi

00:19:46here, pi

00:19:48pi radian

00:19:51so delta phi feeling, say delta phi

00:19:54name, phase difference

00:19:57delta phi unit, say degree

00:20:00or radian

00:20:03when delta x

00:20:06what was the meter or centimeter?

00:20:11meter or centimeter

00:20:22now, let me show you another example of EMW

00:20:25this, let me show you this

00:20:26this too, let me show you this

00:20:28both hands, tell you how many degree

00:20:3090, now let me show you this

00:20:32electric field and magnetic field

00:20:34ok?

00:20:35phase

00:20:37phase

00:20:39phase

00:20:4190 or 0?

00:20:4390 or 0?

00:20:44answer is phase difference 0

00:22:00Art difference ki feel a gai, face difference ki feel a gai.

00:22:03Ab dono ko kya karte hai? Connect.

00:22:07Bada-bada aayi hai.

00:22:10Relation.

00:22:12To formula ho ta hai.

00:22:14Aaj puri gyaari vhi class hai.

00:22:16Delta Phi, 2 pi by lambda into delta X.

00:22:22Delta Phi korn hai?

00:22:24Face difference.

00:22:25Delta X korn hai?

00:22:31Path difference.

00:22:33Koji eek čeiz pata ho,

00:22:35to doosri čeiz nikaali ja sakti hai.

00:22:40In fact, gyaari vhi class mein to time difference hi batate hai.

00:22:43Or result achcha dekho.

00:22:45To ye bhi hoota hai.

00:22:51Bilkul bachit bant karo.

00:22:53Padhai ki taraf ao.

00:22:54Tho'di-tho'di bolti rhooghe to subject khatam hoota hai.

00:22:58Isleep ekdom serious ho ke suno.

00:23:00Pahla lecture hai.

00:23:01Ache se dimahag me batheye baatinggi.

00:23:03Ikeek sawal sol hooga.

00:23:05Aagli lecture se DPP milegi.

00:23:06Module karna hai.

00:23:07Badhiya tiyar hi ho jayegi.

00:23:10Yee dekhi hai.

00:23:12Ab, isme delta Phi.

00:23:15Face difference.

00:23:17Delta X, path difference.

00:23:24Delta T, time difference.

00:23:28T, time difference.

00:23:35Yee wala relation, yee se aaya hai.

00:23:37Agar aankhae khol lehen, board pe, dekhiye board per.

00:23:402 pi ko yaan bheze dijiye.

00:23:412 pi ko yaan bheze dijiye.

00:23:432 pi ko yaan bheze dijiye.

00:23:45Cross to bolo, kya hojae ga?

00:23:452 pi by lambda into del X.

00:23:49Wohi se hai.

00:23:50Sir, yee time difference kya hootahe?

00:23:52Aray, sab ek hi baat hai.

00:23:54Ab tu fir sunna.

00:23:56Thakki te dimahag me kaahni baathe.

00:23:58Kaahni baathegi, imagination aayega.

00:24:01Yee dekhna.

00:24:02S1 se ek wave nikali.

00:24:04P per pahunchi.

00:24:06S2 se ek wave nikali.

00:24:08P per pahunchi.

00:24:10Ab, ek ek baat samajna.

00:24:12Kya douno ke rastte berabar hain?

00:24:14Matlab kya aya?

00:24:16Path difference.

00:24:18Ram, da, shiambara.

00:24:20Path difference.

00:24:21Path difference se kya hohega?

00:24:23Face difference.

00:24:25Achha, time difference bhi hai.

00:24:27Douno nikale 10 baje thay.

00:24:29Yee pahuncha 10 bache ke 2 minute par.

00:24:31Yee pahuncha 10 bache ke 3 minute.

00:24:33Kyo sir, berabar kyo nahi pahuncha ek saath?

00:24:36Rastta alag-alag hai na?

00:24:37Speed to same speed of light.

00:24:39P per rastte ki lambai.

00:24:41To batao.

00:24:42Chunki douno ke biecho me path difference hai.

00:24:46Path difference se kya aya?

00:24:47Time difference.

00:24:49Or unse kya aya?

00:24:50Face difference.

00:24:51Tino apas me interconnected hai.

00:24:55Or bataayi sir,

00:24:57Or mary visualization bhaheyga.

00:24:59If I think so, if I think so, they are 5, this is S1, S2, now we have to reach B. Now, tell yourself, who is going up? Same. So, it means DLX? Zero.

00:25:15If you go up to 10, then reach one, because the road was the same, the speed was also, and the time difference is zero. And think if DLX is zero, then DL5 is also, if there is one thing, then the rest can be left, and the rest can be left, and the rest can be set.

00:25:42If I sit here, like I am standing here, then one, I have a wave from this speaker, one is coming from this speaker, two sound waves, one is less, one is less, one is less, one is less, so tell me what happened, part difference, okay, time difference also will happen, both sound waves will be same in the medium, this means time difference will happen, part difference will happen, time difference will happen, and what will happen, phase difference.

00:26:11If you understand, you'll see some kind of things, about this, when you see one thing, you'll see one thing, since one thing, you'll see one thing, you'll see one thing, one is less, so tell me what happened, right, if I make this one thing, just tell me what happened,

00:26:21we can do something like this.

00:26:25Let's write quickly.

00:26:28Don't say it, it's not.

00:26:31Let's write.

00:26:33Capital T total time.

00:26:36One wave of the whole chakra is lambda.

00:26:39One wave of the whole chakra is T.

00:26:42That is capital T.

00:26:44Time.

00:26:51Go ahead.

00:26:53Let's write.

00:26:55Example.

00:26:56If you think that I know delta phi,

00:27:00then I can get delta x.

00:27:04If I know delta x,

00:27:07then I can get delta phi.

00:27:10Let's see.

00:27:12Let's see.

00:27:13If anyone knows something else,

00:27:15others can get out.

00:27:16It can be done.

00:27:17Don't go sit.

00:27:18Don't sit.

00:27:20Don't sit.

00:27:21Don't sit.

00:27:22Cutting is going to be done.

00:27:24Don't sit.

00:27:25Don't sit.

00:27:26Don't sit.

00:27:27Don't sit.

00:27:28Don't sit.

00:27:29Don't sit.

00:27:30Don't sit.

00:27:31Don't sit.

00:27:32Delta phi.

00:27:332 phi by 3.

00:27:352 phi by lambda.

00:27:382 pi से 2 pi cancel, बता delta x कितना, lambda by 3, delta x कितना, lambda by 3, तो ध्यान रखिए, अगर आपको कोई भी एक चीज पता है, तो आप दूसरी चीज निकाल सकते हैं, दूसरे में देखिए, delta 5 बराबर,

00:28:012 pi by lambda into del x, del phi नहीं पता, 2 pi by lambda, del x कितना, 2 lambda, lambda से lambda कटा, 4 pi, 4 pi, तो अगर कोई भी एक चीज पता है, तो दूसरी चीज उससे find की जा सकती है,

00:28:24अब यहाँ दस सेकिंड का ब्रेक लें, दौनों टम्स को दिमाग में बैठाएं, एक है path difference, path difference का best example,

00:28:34राम चला 10 मीटर, शाम चला 12, path difference दो, path difference से क्या होएगा, phase difference,

00:28:43दोनों के बीच में connection आना चाहिए, क्या ही बात ओके है क्या, path difference मीटर में चलता है, phase difference,

00:28:52रेडियन में चलता है, चाहिए, आगे बढ़ते हैं, counting करवा रहे हैं, क्या होता है, एक physical attendance होती है,

00:29:02आप machine से करते हैं, वो digital attendance है, match भी करना चाहिए data, नहीं तो पता चला कि भाई, अब mismatch हो रहा है, कोई बच्चे पंच नहीं कर रहे हैं, तो यह सब हमारे पास पूरा record रखना पड़ता है,

00:29:14कि भाई, physical attendance, यह counting है, इसे कहते हैं, physical attendance, आप जो थम से लगाते हो, वो digital attendance है, data mismatch करके हमें पता चलता है, कि अच्छा भाई, बिल्कुल सही चल रहा है setup, आज 2700 बच्चे एंटर करें, आज पूरे पूरे बिल्डिंग में एक एक बच्चे को क्लास में जाके गिना जाएग

00:29:44आपको लगता है सिरफ पढ़ाया घर गए, पढ़ाया घर गए, पूरा system क्योंकि आपके मातापिता को यह सब को जवाब देना पड़ता है, कि भाईया, test में नमबर नहीं आ रहे, भाईया, attendance दिखाईए, test result दिखाईए, तब उनसे बात कर सकते हैं, बच्चा आई नहीं �

00:30:14लिखिए, interference, interference, अब आप पर सेडिंग डालिए, interference, आज केवल ग्यारवी क्लास है, अब क्या हो रहा है, वो देखिए, सब लोग देखें, अब चीज़ें हो समझ में आएंगी, अब S1, S2, सर पांच्छे बार बोल लिया, S1, S2 क्या है, source, सर यह आप क्या बोल रहे हो, कि �

00:30:44ने ऐसे कैसे बना दिया, बोटनी जिलोजी में तो नहीं है कोई सेम टॉपिक, ऐसे पांच-पांच टॉपिक सेम होते तो मजा आ जाता, तो यह आप बार बोल लियो, 11 का पड़ा रहा हो, फिर बार बी में, इसके पीछे भी तो सर बात बताओ, मन में आ गया, बोटनी में �

00:31:14अगर यह दो सोर्स, स्पीकर हो गए, तो साउंड वेव, 11 का चेप्टर बनेगा, और अगर यह दो सोर्स, लाइट के हो गए, तो बार बी का चेप्टर बनेगा, लाइट वेव का इंटरफेरेंस, इतनी बातें सीखिए, तब मजा आता है, अच्छा, 11 वाला, साउंड वे�

00:31:44अब देखिए, आप P पर आ रहे हैं, S1 से वेव आई, S2 से वेव आई, क्या यहाँ पर दौनों का रस्ता सेम है, नहीं, क्या पैदा होगा, पार्ट डिफरेंस, पार्ट डिफरेंस से क्या होगा, फेज डिफरेंस, माना इस वेव का अम्प्लिट्यूड A1 है, सर अम्प्ल

00:32:14910 का है, परसर नहीं आता, यह देखिए, अम्प्लिट्यूड कहलाता है, S2 से जो वेव आ रही है, उसका अम्प्लिट्यूड A2 है, P पे जाके दौनों क्या कर रहे हैं, सूपर इम्पोस, तो कितने बढ़िया बढ़िया शब्द बोल, तब है फिजिक्स पढ़ने का मज़

00:32:44ऐसी कोशिश करना, 3-3 मिनिट, 4-4 मिनिट, केवल डिस्क्राइब कर सिचुएशन को, ऐसा बढ़िया समझ में आएगा, कि चीजें आपको दिखेंगी, कि हाँ यार, मैं विजुलाइज कर पा रहा हूं, सर, अब बताईए, यहाँ पे जाके दौनों क्या करेंगे, सूपर �

00:33:14एटू स्क्वाइर, 2-A1-A2, कॉस्ट डिल्टा फाई, सर, चेहरे पे हलकी सी स्माइल आ गई, क्यों सर, क्यों आ गई, अरे सर, यह तो वेक्टर फॉंबल आंसर है, बिल्कुल वैसे ही दिख रहा है, मतलब मुझे अलग से याद करने के आवशक्ता, नहीं है, पर यह क्या

00:33:44उस नई वेव का, यह क्या है, रिजल्टेंट एंप्लिट्यूद, और सोचिए इसका भी एक स्पेशल केस भी होताते थे पीके सर, अगर दोनों फोर्स बराबर हो जाएं, तो पता है, रिजल्टेंट का एक और आंसर है, 2-A, कौन सा सही है, उपर वाला या नीचे वाला, �

00:34:14साथ साथ में लिखते हैं, बिल्कुल ही पॉस हो जाते हैं, जब लिख रहा हूं, उस समय लिखे हैं, रिजल्टेंट एंप्लिट्यूड, यह एंप्लिट्यूड है, यहीं से बात आती है, इंटेंसिटी की, ग्यारवी ख्लास में सिखाते हैं, इंटेंसिटी जो होता है, व

00:34:44nd i resultant i1 plus i2 plus 2 root i1 i2 cos delta 5

00:35:04derivation नहीं किया वेशकता है

00:35:06इसलिए direct याद होना चाहिए

00:35:08थोड़ा ध्यान से याद करिएगा पर

00:35:12एक amplitude और एक क्या है intensity

00:35:15सब दौनों में कोई relation होता है क्या

00:35:18intensity और amplitude

00:35:20intensity is directly proportional to

00:35:24amplitude by square

00:35:26और यहाँ भी अगर

00:35:31if both source have

00:35:35same intensity

00:35:40तो formula आजाएगा i resultant

00:35:464 i0

00:35:48cos square del 5 by 2

00:35:53अब 2 minute यहाँ रुकता हूँ थोड़ा समझिएगा

00:35:59formula याद करना अलग है पर formula को समझ के apply करना आना चाहिए वो बढ़िया है

00:36:09डिल्टा 5 भूल गए हो बापिस लिखें डिल्टा 5 होता है phase difference

00:36:15relation बापिस चिपका दें 5 पाल लिखने में भी कोई शरम नहीं है

00:36:19डिल 5 बराबर

00:36:21टू पाई बाई लेम्डा इंटू डेलेक्स अब बताई यहां तक क्या कि अब मालो यह याद नहीं हो रहा सार यह अलग लग रहा है थोड़ा सा दिमाग लगा दे सार आपने उपर क्या लिखा हुगा है

00:36:39intensity amplitude का square होती है square यह याद है कर दे square दो का square चार कौस का square बहुत चीज़ें जुड सकती है आप विलकुल ही रट्टा बाजी करो तो अलग है अब आपको यह formula बोलना आना चाहिए सरी क्या चीज है मेरे पास दो bulb है पहले बल्ब की intensity आईवन है दूसरे बल्ब की intensity और जब किस

00:37:09So this is which formula?

00:37:11Resultant intensity is the formula.

00:37:13So remember,

00:37:15sir, is it the upper or lower?

00:37:19When you have to put it?

00:37:21When you have to put it?

00:37:23When you have to put it?

00:37:25When you have to put it?

00:37:27When you have to put it?

00:37:29If you have to put it in the question,

00:37:31then we will do it.

00:37:33Let's do it.

00:37:35Okay.

00:37:37Type of Interference.

00:37:39Table.

00:37:41It will come here.

00:37:45Constructive Interference.

00:37:53Destructive Interference.

00:38:01Constructive.

00:38:03Let's write all the conditions.

00:38:05Constructive.

00:38:07Constructive.

00:38:09Phase difference.

00:38:11Even multiple of pi.

00:38:13Bye.

00:38:43I'll explain it.

00:38:45Let's do it.

00:38:51Now, I'll explain it.

00:38:55But please remember it.

00:38:57Bring it back.

00:38:59Pray it quickly.

00:39:01Now I will explain all this, but you should remember all this, brother.

00:39:09We will remember and we will learn quickly.

00:39:12Think about it, I will remove everything in the paper, then it will be clear.

00:39:31Think about it, I will remove everything in the paper, then it will be clear.

00:39:51Think about it, I will remove everything in the paper, then it will be clear.

00:40:08Think about it, I will remove everything in the paper, then it will be clear.

00:40:15Okay?

00:40:30Oh

00:40:49I have a poor table

00:40:51.

00:41:11.

00:41:15.

00:41:16.

00:41:17.

00:41:18.

00:41:19.

00:41:20.

00:41:21.

00:41:21When pi becomes even multiple, what do you call the interference? Constructive.

00:41:28Here the sound is straight. Okay, the sound means sound wave. Bright spot means light wave.

00:41:37Both are being covered. Maxima, intensity, max. This means these are all words.

00:41:44Then you need to put it. Which interference is happening? Constructive.

00:41:50Let me tell you, sir, how is it? Let me tell you. Which one? Amplitude.

00:41:55How is the multiple? Even.

00:41:58So, the formula is R. Don't write. Don't write. Don't write. Don't write.

00:42:01A1 square plus A2 square plus 2 A1 A2 cos phi.

00:42:08Now, the problem is cos 0, cos 2 pi, cos 4 pi.

00:42:12How much will we give? 1.

00:42:14So, under root of A1 square plus A2 square plus 2 A1 A2.

00:42:20A1 A2.

00:42:21Now, let's look at this. What is this? A1 plus A2.

00:42:23A1 plus A2.

00:42:25A1 plus A2.

00:42:26A1 plus A2.

00:42:27A1 plus A2.

00:42:28A1 plus A2.

00:42:29A1 plus A2.

00:42:30A1 plus A2.

00:42:31A1.

00:42:32A2.

00:42:33A2.

00:42:35A2.

00:42:36A2.

00:42:37Now, what is intensity too, this?

00:42:38A1 plus A1 plus A2 plus

00:42:412 root i1, i2, cos delta phi.

00:42:42Cos delta phi.

00:42:44Cos value?

00:42:451.

00:42:46Now,�� yet see whose whole square is.

00:42:48By stop telling Menden線 x.

00:42:51Check. Check. Check. A plus B ka holy square. I don't remember A plus B ka holy square.

00:42:57A square plus B square plus. Check. Root I1 ka square. I1. Root I2 ka square.

00:43:07Plus 2 A B. And tell delta X how come from that? Tell delta 5.

00:43:152 pi by lambda in 2. Delta 5. Pi ka ka ka multiple? E1.

00:43:23This is general value. 2 and pi. 2 and pi. This is general value.

00:43:28General value what is happening? Now let's put it in N.

00:43:32N to 0. N to 1. 2 pi. N to 2. This is general value.

00:43:40So delta 5 is 2 N pi. 2 pi by 2 pi. Lambda here. Del X how come from? N lambda.

00:43:51Look. Look. All results are gone. But no derivation is not asking. You need to remember the result.

00:44:02Constructive interference. You need to know this. Now listen to sentence. If there are two waves in part difference.

00:44:100. Zero came. So you need to know this. It will be constructive. Ram and Shyam.

00:44:16It will be reached together. Sir Del X 0. What will be constructive?

00:44:21When part difference. 0 lambda. 2 lambda. 3 lambda. Then it will be constructive interference.

00:44:29In the mind, set it in the mind that when it is constructed, the amplitude is maximum. A1 plus A2, the intensity is maximum, root I1 plus root I2 is whole square, the sound is hard to hear, the spot is bright, it is called maxima.

00:44:49If you remember it, what is it? What is it? If you remember it, what is it? What is it? What is it?

00:45:19If you remember it, what is it? What is it?

00:45:49If you remember it, what is it? What is it?

00:45:53Change a little bit. If you remember it, September, October, November, December, January, February, you have to study it.

00:45:59Like I said, I have to study it.

00:46:00I love the work.

00:46:01I do not study the work.

00:46:03Let's study it.

00:46:05Here, I will study it.

00:46:06I will study it.

00:47:33बीटा

00:47:51नीट में आया हुआ है

00:47:52थोड़ी सी कैलकुलेशन ज्यादा है

00:47:54अब

00:47:59सीधा है डरावना एक्सपेशन सौल नहीं होगा

00:48:01पता है क्या करना पड़ेगा

00:48:03step 1

00:48:18पहले क्या निकलना पड़ेगा

00:48:21i max

00:48:22i max बोल

00:48:23root i1

00:48:25plus root i2 का

00:48:27whole square

00:48:28बोट पे देख बोट पे देख

00:48:30पहले step 1 क्या निकलना पड़ेगा

00:48:32i max

00:48:33जल्दी से चिल्ला है का i1 कितना है

00:48:35i2

00:48:36i2

00:48:38तो i1 है बीटा और i2 है वन

00:48:42a मिल्स बी का हूल स्क्वाइर

00:48:47जागेगा और और i 2 है वन

00:48:482ab, beta plus 1 plus root 1 to 1, 2 root beta, i max आ गया, अब i min निकल, i min निकल, root i1 minus root i2 का whole square,

00:49:08i1, beta, i2, 1, a square minus b square, a square plus b square minus 2a, क्यों हो गया, beta plus 1 minus 2 root beta,

00:49:25हाँ, wavelength से, दौनों की lambda है ना, सेम ही तो है,

00:49:42तो मतलब superimposed होंगी, हम जो पढ़ रहे हैं, वो क्या पढ़ रहे हैं,

00:49:46same frequency, same wavelength, बिलकुल, coherent source की बात कर रहे हैं आगे जाके,

00:49:55अब यह क्या आगया, आपके पास, i min आ गया, आराम से करिए,

00:50:04अब उस डरावने expression में value रखिए, सीधा उसको देखेंगे,

00:50:08तो घबरा जाएंगे, i max minus i min, upon i max plus i min,

00:50:16बताएं क्या बात ok है, अब i max रखिए, beta plus 1 plus 2 root beta,

00:50:33अब ध्यान से देखना, यह minus है, तो यह minus beta हो जाएगा,

00:50:54यह minus 1 हो जाएगा, 2 root beta, 2 root beta, 4 root beta, यह देखिए,

00:51:022 root beta, 2 root beta कटेगा, beta plus beta, 2 beta, 1 plus 1, 2,

00:51:10नीचे से 2 common ले ले, beta plus 1,

00:51:24थोड़ी सी महस जादा थी, बाकी physics नहीं अतनी जादा,

00:51:31पर आया हुआ सवाल है, इसलिए आना चाहिए, approach,

00:51:36और systematic करिए, step 1, i max निकाला, step 2, i min निकाला,

00:51:41और फिर, आप उसमें expression में value डाल दीजिए,

00:51:48बोलिए, एक मिनिट ले, एक बार table को वापिस याद करें,

00:51:54पूरा review करें, यहीं बैटकर, जल्दी याद हो जाएगा,

00:52:00एक मिनिट लें, दो मिनिट, पूरा revise करें,

00:52:03दीरे दीरे दिमाग में उसको बैठाईए, बार बार पढ़कर,

00:52:13अगली class, Thursday को है, 31 तरिक को, उस दिन सुबह जल्दी आईएगा,

00:52:215-10 मिट पहले, 6-55, तो क्या होगा,

00:52:25दौनों बैच को एक साथ, बराबर चल रहे हैं,

00:52:27दौनों को एक साथ बैठाऊँगा, सुबह 6-50,

00:52:30जल्दी आने से क्या होगा, व्यवस्त अच्छे से हो जाती है,

00:52:33बीच में मर्ज करते हैं, तो क्या होता,

00:52:35जैसे यह 5-6 लड़कियां बैठी है, यह 2 बैठी है,

00:52:38वहां 3 लड़कें बैठे है, है न,

00:52:40तो क्या होता, फिल कहते हैं, खिसको,

00:52:42तो सब फिल मुव ही घढ़ानाई, नहीं सर, जगई नहीं,

00:52:46to merge. So, in the morning, the first class is to merge. So, in the morning, the first class is to merge.

00:52:52The systematic is going on, every bench is going on, the capacity is going on.

00:52:56Now, what is the 5th? Now, the 2th bench is going on. So, everything is going on,

00:53:02the back is going on. So, in the morning, the second class is going on.

00:53:08All the students have to move. In 6 days, the school fell on.

00:53:12Both, each of the staff had to look, calculate, room capacity, all are set.

00:53:17Teacher, sir, no change? No change, nothing.

00:53:20Anything.

00:53:26Hey, that will be a little few days, 10 days before this.

00:53:31In other words, there is no problem in the whole world.

00:53:35If I will study Electrodynamics, then I will study all of the 2700 children.

00:53:40All of them. Electrodynamics, Electrocurrent, PLC, modern.

00:53:45So whether you are star or enthused or achiever pro,

00:53:50any of them, all of them.

00:53:52With any child, there is no discontinuity, no other person.

00:53:57You will check in October, December, February.

00:54:01J.C. Sir Organic will study all of the 2700 children.

00:54:07You will study IOC.

00:54:09Every child will study IOC.

00:54:12Whether you are 11th or 12th or drop.

00:54:15No one is not.

00:54:16Leader, Achiever, Master pro, Elite, Alpha Achiever, Achiever plus.

00:54:23No one is not.

00:54:24This is our unique point.

00:54:26As a child, the child is enrolled, the child is studying offline,

00:54:31all of them, one team, all of them.

00:54:34Nothing is at all.

00:54:36So the child doesn't feel like that.

00:54:37That is a child studying, that is different.

00:54:39That is a child studying, that is studying Electrodynamics,

00:54:42that is something else.

00:54:43That is no difference.

00:54:44Today, not.

00:54:45We will not have any difference.

00:54:47We will study so much as we can study.

00:54:50We will study.

00:54:51It is not that, brother, children are growing.

00:54:53Electrodynamics, all of them.

00:54:54I don't have to study.

00:54:55I don't have to study.

00:54:56I don't have to study.

00:54:57I don't have to study.

00:54:58I don't have to study.

00:54:59Modern physics, semiconductor, PL.

00:55:00Sir is studying.

00:55:01So star batch, achiever pro, leader, enthuse.

00:55:05Enthuse, enthuse, class 12.

00:55:07So there is also studying.

00:55:08So there is a symmetry.

00:55:10This is all it has not been at all.

00:55:13So I am now carrying.

00:55:14I am now and I am now and I am now.

00:55:19Then what I am now?

00:55:20Value.

00:55:21Now fast.

00:55:22Stayed in the table.

00:55:24Do not take it.

00:55:25Say now.

00:55:26Let go.

00:55:29Let go.

00:55:30Ready.

00:55:32Finally.

00:55:33Constructive and destructive.

00:55:35I am a big man.

00:55:36I am a big man.

00:55:37constructive or destructive

00:55:46don't talk about it, don't talk about it, don't talk about it, don't talk about it,

00:55:59I have not given time to talk about this, I have not given time to talk about this.

00:56:21I have given time to talk about this, this wave is given time to talk about this.

00:56:30I have not given time to talk about this, but I will tell you that the situation is not coming.

00:56:35This is what is written further, this is called amplitude.

00:56:42This is called phase, this is called phase, this is called phase.

00:56:51This is a basic thing.

00:56:53Equation in the next one is what is amplitude.

00:56:57Now tell me, the first wave, the first wave of amplitude is how much?

00:57:02Three, the second wave of amplitude is how much?

00:57:06Four, this is what is phase.

00:57:10This is what is phase.

00:57:12What is phase?

00:57:13What is phase?

00:57:14But what do we need?

00:57:15Phase difference.

00:57:17What do we do?

00:57:19We have to minus the phase.

00:57:22Let us minus the phase.

00:57:24Let us understand logical.

00:57:26Don't approach the direct approach.

00:57:29Fundamentals.

00:57:30First phase, the second phase, the second phase.

00:57:34Then phase difference.

00:57:36How much?

00:57:37How much?

00:57:38Omega t plus pi by 2 minus omega t.

00:57:42So, here is pi by 2.

00:57:43Here is pi by 2.

00:57:45Here is your phase difference.

00:57:47Here is your phase difference.

00:57:51Phase difference.

00:57:52Here is pi by 2.

00:57:57Here is pi by 2.

00:57:59一个セmatyer

00:58:00Here is the resultant amplitude.

00:58:02R ka formula under root of a1 square plus a2 square 2 a1 a2 cos delta phi.

00:58:14A1 3, A2 4, 2, 3, 4, cos 90, cos 90 is 0.

00:58:44अगले टन से होंवक मिलेगा, आज कुछ भी 12 नहीं पढ़ाई है, 12 तो अगले लेक्टर से आएगी, हाईगन वेव थियोरी, आदा घंटा थोड़ा सा बायो आएगा वो, हाईगन वेव थियोरी, स्फेरिकल वेव फ्रंट, सिलेंड्रिकल वेव फ्रंट, फिर उसके बाद आ

00:59:14यह common है, दोनों में, 11 वी में भी, 12 वी में भी, दोनों में common है, वहाँ sound waves का interference है, यहाँ, यहाँ light wave का interference है, बढ़ू के आगे, जल्दी आओ, चलो,

00:59:41आगला question लेखो,

01:00:11अब यह भी एक बढ़िया सवाल है, how to calculate number of maxima और minima,

01:00:28यह भी बढ़िया standard सवाल है, और दोनों जगे बनता है, इसको बढ़िया तरीके से समझाएं,

01:00:41चलो, अब सीखना, आदा सवाल तो मैं करा चुका हूँ, और आदा सवाल अब देखना है,

01:01:03सभी लोग बोड़ पर देखना, last question है, अच्छे से समझिएगा, सबसे पहले यहाँ देखिए, क्या S1 से wave आएगी,

01:01:12S2 से wave आएगी, जल्दी से बताईए part difference, अभी हमने किया था, आदा सवाल, यहाँ बताईए part difference,

01:01:19जीरो, यहाँ सोचके बताईए, S1 से wave आई, S2 से wave आई, जादा कौन चला, S1, तो part difference,

01:01:332 lambda, यहाँ part difference, अब ध्यान से सुनिएगा, काम की बात, यह देखिए, टेबल में आते हैं, यह रहिए,

01:01:49टेबल क्या घह रही है, उसको देखिए, जब जब part difference, 0, lambda, 2 lambda होता है,

01:02:00तब तब constructive interference होता है, बात दिमागे में ठाईए, जब जब part difference,

01:02:06मेरे भाई, जब जब part difference, 0, lambda, 2 lambda होता है, तब तब constructive,

01:02:13what will be maxima, where will be maxima, maxima, maxima, two lambda is, but one more thing, maxima is, maxima is, part difference is, zero, lambda, two lambda and so on, sir, zero is, two lambda is,

01:02:39Josaijippa, you see, this is how this is, just go, whether a, lambda is, where will hi, sir, Guruji, here is, somewhere here, then here is,Okay here is, what will be, here must be here, what will, there must be, what will and the circle is, what will be zero and two lambda, here is part difference, lambda, sir, how will you learn, here it says,

01:03:06sir, how much part difference? Here, say here, here, see here, zero per maxima, two lambda per maxima, means somewhere where lambda will come, means between both of them, where lambda will come. Sir, check here, this zero, this two lambda, then here, lambda. Sir, check here, zero, two lambda, then here too.

01:03:30Here, check here, zero, two lambda, then lambda. Now, tell you, how much maxima count? How much maxima count? 1, 2, 3, 4, 5, 6, 7, 8. So, total maxima, 8.

01:03:538, maxima.

01:04:23I'm going to the table. Look at this. Zero and lambda, there is a lambda by 2, which is 1.5. Lambda and 2, this is 2.5. This means,

01:04:41Miss Love, every 2 lambda, every 2 lambda, every 2 minima, every 2 minima, every 2 minima, what happens? 1 minima. Look, check here, 0 lambda, 0.5. 1 and 2, 1.5.

01:04:591.5. Miss Love, Miss Love, every 2 consecutive maxima, what will become 1? 1 will become 1? Let's check here, let's check here, let's check here. Look, these 2 maxima.

01:05:13So, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here, here
