00:00:00According to, according to Maxwell, according to Maxwell, comma, light waves are electromagnetic waves.

00:00:22According to Maxwell, light waves are electromagnetic in nature, electromagnetic waves, electromagnetic waves, comma, electric field vector,

00:00:52electric field vector, magnetic field vector, electric field vector, magnetic field vector, and direction of propagation.

00:01:10And direction of propagation, all are perpendicular to each other.

00:01:25In electromagnetic wave, electric field vector, magnetic field vector, and direction of propagation, all are perpendicular to each other.

00:01:40Chalik.

00:01:42Chalik.

00:01:42वैसे तो पूरा EMW अपने syllabus में है.

00:01:46Diagram बढाईएगा.

00:01:51छोटा सा chapter है.

00:01:52अब आज आप देखना, जर्वहाज गंते में तो,

00:01:54अल्मोस्ट पूरा ही हो जाएगा.

00:01:56नुमेरिकल करोगे तो आदब घंटा और अगले में discussion में लगेगा.

00:01:59and the rest of the chapter is a small and easy chapter.

00:02:04And I think that one hour of the lecture is two questions in 2015.

00:02:10There were two questions in the rear optics.

00:02:12There were six questions in the rear optics.

00:02:14And there were two questions in the lecture.

00:02:16And in one lecture, how many questions are there?

00:02:18Two questions.

00:02:20So EMW, three things, one second thing is perpendicular.

00:02:28Three things, one second thing.

00:02:30Electric field vector, magnetic field vector, and direction of propagation.

00:02:36Now, let's see what I'm saying.

00:02:42Electric field is how many degrees?

00:02:4790 degrees.

00:02:48Electric and magnetic.

00:02:50Electric field is more than the magnitude.

00:02:52Our retina is more than the electric field.

00:02:56Sensitive, those are the whole chapter.

00:02:58So we spoke from the whole chapter.

00:03:00Electric field, so we hear from the whole.

00:03:02We talk from the whole chapter.

00:03:04The whole thing is 90 degrees.

00:03:06It's not the electric field.

00:03:08So you talk about electric field.

00:03:10If your light goes on,

00:03:12the way to the direction of propagation,

00:03:16The direction of propagation is x.

00:03:20तो सोचिये, Electric field कहां होगी?

00:03:23Electric field को होना है 90 degree compulsory है.

00:03:27तो बता कहां हो सकती है?

00:03:29Y में, Y में, बिल्कूल ठीक बात.

00:03:35Electric field oscillate कर रही है.

00:03:37Os 준�ate का मतलब समझते हैं?

00:03:39Osзд 충ite, इस तरह से oscillate कर रही है.

00:03:42यह देखे, यह oscillation हो रहा है,

00:03:44Electric field का, यह oscillation है.

00:03:46Y में.

00:03:47A boy says,

00:03:49Z will be able to die.

00:03:50This is a great thing.

00:03:52Why?

00:03:52Z will be able to die 90 degrees.

00:03:59A boy says,

00:04:01No sir,

00:04:02Ok,

00:04:02What can I say?

00:04:04Sir,

00:04:05Why don't you say,

00:04:07YZ plane where company could die?

00:04:11YZ plane where company could die?

00:04:15Why don't you say,

00:04:16YZ plane where company could die?

00:04:17I think I should have thought about this.

00:04:19If you think that wave x is going to go,

00:04:21this wave x is going to go,

00:04:23this is y-z plane,

00:04:25this y-axis is z.

00:04:27Now, can you explain that plane is perpendicular?

00:04:31This is where it is.

00:04:33Where it is, where it is.

00:04:35Where it is.

00:04:41We can do it.

00:04:47This is the page.

00:04:49This is the y-z plane.

00:04:51This is the electric field.

00:04:53The wave is going on your way.

00:04:55Can you explain that?

00:04:57Can you explain that?

00:04:59Can you explain that?

00:05:01Can you explain that?

00:05:03Can you explain that?

00:05:05Can you explain that?

00:05:07The wave is traveling along x.

00:05:09My hand is the wave propagation.

00:05:11This is which plane is?

00:05:13Y-z plane.

00:05:15Y-z plane is x-axis.

00:05:19Tabern

00:05:39How can you describe its light?

00:05:41light को बोलते हैं

00:05:43unpolarized light

00:05:45electric field के

00:05:47vibration यह कहते है

00:05:48vibration of electric field

00:05:51electric field

00:05:52oscillate कर रही है ऐसे

00:05:54electric field के oscillation

00:05:56y में भी, z में भी

00:05:58y, z में कहीं भी

00:06:00इस तरह की light को क्या बोलते है

00:06:02unpolarized light

00:06:04यह जितना भी आप प्रकास देख रहे है

00:06:07sunlight, tube light, torch का

00:06:09प्रकास, tube light यह सब कैसी है

00:06:11unpolarized

00:06:12अगर अच्छा समझ में आएगा

00:06:15बाद में लिखिएगा

00:06:16if vibration

00:06:19of electric field vector

00:06:21is

00:06:23restricted

00:06:25only in one direction

00:06:30अगर

00:06:33electric field के vibration को

00:06:35restrict कर दिया जाए

00:06:36केवल एक दिशा में

00:06:38then

00:06:39such a light is called

00:06:42polarized light

00:06:45कहने का क्या मतलब है

00:06:49क्या कहना चाता हूँ

00:06:51अगर मान लो

00:06:53wave जा रही है

00:06:54x में

00:06:55अब आपने

00:06:56electric field को क्या कर दिया

00:06:58restrict

00:06:59भाई कोई एक दिशा चुन ले

00:07:01कोई एक चुन ले

00:07:03तेरी मर्जी पड़े

00:07:04वो कह सर मैं तो y में रहूंगा

00:07:06ठीक है

00:07:07बता अब सिरफ किस में रहेगा

00:07:10y

00:07:11सिरफ y

00:07:12only y

00:07:14इस तरह की light को क्या बोलेंगे

00:07:16polarized light

00:07:19वो कहेगा नहीं सर

00:07:20मैं y में नहीं

00:07:21मैं तो किस में रहना चाता हूँ

00:07:23z में

00:07:25मेरा direction of propagation है x

00:07:27मैं सारे के सारे vibration किस में रखूँगा

00:07:30z में

00:07:31तो keval क्या होगा

00:07:33z

00:07:34आप definition पड़ी आपको समझ में आएगा

00:07:38if the vibration of electric field

00:07:41is restricted

00:07:43only in

00:07:44one direction

00:07:46only in one direction

00:07:48इस तरह की light को क्या कह जाएगा

00:07:50polarized

00:07:51प्रतिबन लगा दिया

00:07:53restriction

00:07:54के भाईया केवल किस में

00:07:56एक direction में

00:07:57either in y or in z

00:07:59पिता जी ने restriction लगा दिया

00:08:02आए न

00:08:03तो 10 बज़े तक आ जाएगा रोज रात को

00:08:06कि रोजे लेट आना मुझे पसंद

00:08:09थेरी मा मुझे रोज गलती है

00:08:11परिशान करती है

00:08:12फोन लगाओ फोन लगाओ इसको कब तक आएगा

00:08:14खाना नहीं खाया फिर वो खाना नहीं खाती

00:08:17मुझे परिशान करती है

00:08:18I will put the phone on my phone.

00:08:20I will not need to go and go.

00:08:23Come on,

00:08:24ten seconds to come.

00:08:26After that,

00:08:28I will see you out there,

00:08:30I will see you out there.

00:08:33I will put the restrictions on my own.

00:08:35Come on,

00:08:36ten seconds to come.

00:08:38I will not like to go.

00:08:41I will not be late.

00:08:42I will not be back.

00:08:44I will put the restrictions on my own.

00:08:46How many times have you reached?

00:08:4810 days ago, we will reach the Father's house, we put the restriction on the vibration of electric wheel vector is restricted only in one direction.

00:09:01What was that?

00:09:03We had to study in the Y, Z, Y, Z, anywhere, in all directions possible.

00:09:09So, we say, Unpolarized.

00:09:11If vibration of electric wheel is restricted only in one direction, then such a light is called Polarized light.

00:09:20In the whole chapter, we have to do this.

00:09:23Unpolarized light to which one?

00:09:30Polarized light.

00:09:32Unpolarized light to the polarized light of the process?

00:09:37Polarization.

00:09:39If you ask, what is the polarization?

00:09:42What is the polarization?

00:09:43One line in the first question.

00:09:46Polarization means, Unpolarized light to the opposite?

00:09:50Polarized light.

00:09:56Unpolarized light to the opposite?

00:09:59Polarized light to the opposite?

00:10:01Polarization.

00:10:02Polarization is not the same way.

00:10:06Polarized light to the same way.

00:10:07Polarization, Kevel and Kevel, Transverse Wave that is the phenomenon of transverse wave.

00:10:14Why is it because in transverse wave, the vibration of the direction of propagation is perpendicular.

00:10:28First note, then I will explain everything.

00:10:32The next test is the date?

00:10:35When is it?

00:10:3831.

00:10:39We are ready to start.

00:10:41We have two weeks.

00:10:42The diffraction is full.

00:10:44I will give you the diffraction.

00:10:45I will give you the interference.

00:10:47I will give you the ray.

00:10:49I will give you the ray.

00:10:51The wave optics is full.

00:10:53The new chapter will start.

00:10:55The polarization will be full.

00:10:57The interference, diffraction, polarization.

00:11:01It will be two or three times.

00:11:03Wave optics will give you full.

00:11:06The new chapter will give you more.

00:11:09It will be late, two or three months.

00:11:11It will be full.

00:11:12The ray optics will give you two or three.

00:11:14The ray optics will give you more.

00:11:16It will keep in mind that.

00:11:18The same thing will come.

00:11:20It will keep in mind that wave optics will give you full.

00:11:22The interference will be full?

00:11:23The question will take over 5-6.

00:11:25The diffraction and polarization will come.

00:15:06one shot में समझ में आ जाएगा

00:15:08मन लगा के देखिएगा

00:15:09आज ही इसके numerical कल लीजेगा

00:15:11कल छुटी भी है

00:15:13खुब पढ़ाई करिये

00:15:15मैं आपको फिर कह रहा हूँ

00:15:16ये समय फिर वापिस नहीं आएगा

00:15:18छुटीयां back to back

00:15:19कल छुटीये कल वापिस चुटीया रही है

00:15:21जितनी पढ़ाई कर सकते हैं

00:15:23करिये

00:15:24दिसंबर जन्वरी में

00:15:26बहुत सारा स्लेबस हो जाएगा

00:15:28इतना रिलेक्स नहीं रहेंगे

00:15:30जितना भी हैं

00:15:31अभी रिलेक्स हैं

00:15:32बहुत जादा अपने पास अभी

00:15:33लोड नहीं है

00:15:34इसलिए जितना रिवाईस कर सकते हैं

00:15:37जो पढ़ लिया

00:15:38उसको इतना रिवाईस करके रख लीजे

00:15:40बाटनी जिलोजी में दो-दो चेप्टर

00:15:42एक-एक चेप्टर तो हो गया होगा

00:15:44देखो आप कहारी हैं

00:15:51पीस-पैस चेप्टर हो चुके हैं

00:15:54तो आप यही सोचिए

00:15:57जैसे कल है

00:15:59संदे

00:16:00अब सबका लग-लग सेट कर सकते हैं

00:16:03या चार चेप्टर बाटनी के पकड़ते हैं

00:16:06केवल पूरे दिन उनकी क्या पढ़ेंगे

00:16:08NCRT तियार करी

00:16:10पोशिश करिए थोड़ा सा

00:16:11थोड़ा डेडिकेशन दिखाईए

00:16:13जब सब बच्चे को पता है

00:16:14पूरे भारत को पता है

00:16:16360 में से

00:16:18340, 345, 350 तो

00:16:21NCRT से ही आएगा

00:16:22एक या दो सवाल इस साल थोड़े से अच्छे आए थे

00:16:25बाकि तो पूरा NCRT फोकस है

00:16:27तो भाई एक बार NCRT को पढ़े ना यार

00:16:3010-12 घंटे NCRT लेकर बैट

00:16:32Physics का Master हूँ

00:16:34क्या कह रहा हूँ

00:16:35Botany Jology पढ़

00:16:36Physics नहीं है

00:16:38कारण है Selection

00:16:39और Selection का आसान

00:16:41सबसे पहला रस्ता जो निकल रहा है

00:16:43वो बायों से निकल रहा है

00:16:44क्यारण क्या बायों की

00:16:46Weightage भी Double है

00:16:47Weightage Double

00:16:48और syllabus Out है

00:16:50कि 350 तो पक्का कहां से टिकेगा

00:16:53NCRT से

00:16:54तो थोड़ा सा इस बात को

00:16:56गंबीरता से समझे

00:16:57कि यार मुझे न

00:16:58ऐसा क्यों नहीं याद है

00:17:00चार चेप्टर की कहीं से भी कोई भी लाइन पूछ लो

00:17:02संभव तो है

00:17:03बार-बार उसको पढ़ेंगे

00:17:05तो क्यों नहीं तयार हो सकता है

00:17:07थोड़ा सा इसको समझीए

00:17:09बात को सभी सब्जेक्ट पढ़ने से काम चलेगा

00:17:12मैं आपको फिर कह रहा हूँ

00:17:13केवल एक या दो सब्जेक्ट के आप भरो से बैठोगे

00:17:16नहीं हो पाए

00:17:17घमामला गड़बड है

00:17:18थोड़ा से इस बात को सीरियसली लीजिए

00:17:20चलिए

00:17:21अब आते हैं ब्रेश्टर लो

00:17:23ब्रेश्टर ने कहा

00:17:24जब लाइट

00:17:26डाइग्राम सासद बनाना शुरू करिए

00:17:29अनपोलराईज लाइट

00:17:33अनपोलराईज का मतलब होता है बनाने में
