00:00:30we have 8 fringes. So, how many fringes do we get out of 400?
00:00:36Is this distance? Is this distance fixed? So, how do we get out of this distance?
00:00:42So, this distance is how we get out of this fringes. So, this is 8.
00:00:49So, this distance is how we get out of this fringes.
00:00:528 lambda d by small d.
00:00:55If the other one is n, then this is n lambda d upon me.
00:01:00So, this d and small d will cancel.
00:01:028 will be 600 nanometer.
00:01:05And this will be n.
00:01:07This will be 400.
00:01:08So, this value will be 8.
00:01:108 will be 8.
00:01:128 will be 8.
00:01:158 will be 8.
00:01:178 will be 8.
00:01:198 will be 8.
00:01:208 will be 8.
00:01:228 will be 8.

00:28:41difference
00:28:42which is the difference of kinetic energy is not the difference of kinetic energy.
00:28:47If the difference is 4,
00:28:49in this energy and work function,
00:28:52the electrons will be maximum of 4,
00:28:56and minimum of zero.
00:28:58If zero is minimum of zero,
00:29:00which will be very much collision,
00:29:02then the whole energy will be lost,
00:29:04and the surface will be removed.
00:29:06But the surface will be removed,
00:29:08the kinetic energy will be zero.
00:29:11If the surface is come,
00:29:13then I am talking about the question.
00:29:15I am talking about this question.
00:29:16If the electron energy got 4,
00:29:18then the surface will be 0,
00:29:20and they are not back.
00:29:21If the kinetic energy is not going,
00:29:23there will be no way?
00:29:24No, but the nucleus of the proton will be in.
00:29:28Those who are zero to the electron emit,
00:29:32but they will not be able to move,
00:29:34and the other will not be able to move.
00:29:36The energy will be given to the electron emission.
00:29:38So this is the electron emission, but the current will not be able to participate in the current, but the other will not be able to do it.
00:29:47So here we have to know that if this is a work, because the E value of the function is higher,
00:29:55then the electron emission will be, and the kinetic energy will be 0 to 4 electron volts.
00:30:12Maximum kinetic energy will be 4 electron volts.
00:30:17So here we have to know that the electron is emitted,
00:30:27having different kinetic energy.
00:30:34All the kinetic energy will not be the same, but the range will be the same.
00:30:38If this is 10 and this is 4,
00:30:40then the kinetic energy will be 0 to 6.
00:30:43Maximum 6 will be the same, but 0 to 6 will be the same.
00:30:48Let us know.
00:31:10So the energy will be the same.
00:31:13One thing.
00:31:15The photoelectric effect,
00:31:191 photon and 1 electron of interaction,
00:31:221 photon and 1 electron of interaction is the same.
00:31:25It is not.
00:31:26It is not.
00:31:27It is not.
00:31:28It is not.
00:31:29It is not.
00:31:31It is not.
00:31:33If the photon of interaction is even zero.
00:31:43orthogon of interaction is zero.
00:31:47That is not one photon gets zero.
00:31:48And when you do this,
00:31:50then the reckons are zero.
00:31:52thothen is zero.
00:31:54One photon is zero.
00:31:56In a second halo.
00:31:57Is there any photon?
00:32:00Water is zero.
00:32:02in the surface of a tonic layer proper place a photo elect electron emission
00:32:09hogar electron image
00:32:13a nickel an electron payment who are not the papa social like auto but
00:32:18barbarian energy at a rate of emission over for a personal other current my
00:32:22participant maker for or a pop rate
00:32:30I like I
00:32:37I have a man though
00:32:45sorry drum to body when I
00:32:51go away to the
00:41:25We have enough energy to get enough energy.
00:41:29If it is enough energy to get enough energy,
00:41:32then electron will be emission.
00:41:34But if this is surface,
00:41:36then electron will absorb the nucleus.
00:41:40If this is energy is more than 6,
00:41:44and this is 2,
00:41:47then kinetic energy is more than 0.
00:41:51It's not a two-zero.
00:41:54We are zero to 4.
00:41:56We are zero to 4.
00:41:57We are zero to 4.
00:41:58Battery is variable.
00:42:00I know betty variable is zero.
00:42:02Zero.
00:42:03We are zero to battery,
00:42:05but these are zero to the battery.
00:42:07So it is zero.
00:42:09This is zero.
00:42:12I can't 0 the variable,
00:42:15but the candlestick energy will be known
00:42:19for the battery.
00:42:20लेजितनों की जल चल जादा दी वह तो यहां पर चलते चलते पहुंच गय

00:44:45come cardo you have a sorry Connie and simple thing is it a lot of TK by battery man malo
00:44:51I put 6 volts, 6 volts, 6 volts, 6 volts
00:44:57battery is one thing.
00:44:58Here is the kinetic energy, 0-4, battery is not
00:45:06going to be, but just like we have 2 volts
00:45:11battery is going to be, so 2 volts
00:45:15battery is going to be electric field, plus
00:45:18a minor, a lot of the topic, so we see
00:45:21that I'm going to have a photoelectric
00:45:23location, watching it, so that I have a
00:45:26pass, my electric field, electric field
00:45:28male electron, a force, a force, a force
00:45:31can give us kinetic energy, kinetic energy
00:45:34key, and the half mv square, a potential
00:45:39difference, Q into V, but I, but I don't
00:45:42know.
00:45:49Here we go.
00:45:50Here we go.
00:45:51Here we go.
00:45:52Then we go.
00:45:53Here we go.
00:45:54Here we go.
00:45:55Let me go.
00:45:59Actually.
00:46:00Here we go.
00:46:01Here we go.
00:46:03Q into E, if we have electric field in this electric field, then the force is called ultra.
00:46:11Q into E, this is the value of E, and this is the force of force.
00:46:17And when it comes to the power of kinetic energy, the power of kinetic energy is called kinetic energy.
00:46:25The charge is called the potential difference, which means that V, V means that V.
00:46:33V means that V means that V means that V means that V means that V means that V means that V means that V means that V is the same thing.
00:46:38So we have two forms of force.
00:46:40Q into E is force and Q into potential difference is kinetic energy.
00:46:46what passes the good score case am I'm a shaklai address of the Marlo is room
00:46:51may have made this world key battery lager the door of the work a beach man
00:46:55that's world get back to the game at the middle of the dust world or there is zero
00:46:59high potential low potential so high is a low key part of kaya electric field
00:47:05yeah right electron is electron electric field electronic electric field
00:47:10a ultra to get a channel again so it's kinetic energy IQ into V into does does electron world
00:47:22in to V this world the other got this electron world so I can't say Bola Dara
00:47:29if you see key kinetic energy but I select on water but as electron water yeah or other
00:47:37electron electron electron electron electron electron volt
00:47:41में यह electron हुआ तो यह क्या बन जाएगा charge
00:47:44V कितना बन गया पचास
00:47:47पचास electron volt alpha particle की kinetic energy है
00:47:53alpha charge कितना होता है 2E
00:47:57तो 50 में से 2E का charge है तो यह
00:48:01तो बन गया charge और यह बन गया उसका V
00:48:04मतलब alpha को 25 volt से चला है
00:48:06तो जो Q into V में Q देख लेना है
00:48:10बाकी बचा हुआ उसका potential difference है
00:48:12kinetic energy में उस वापस से सोचें
00:48:14हमने जो बात की है वो
00:48:17battery 0 है
00:48:19kinetic energy जो मैं example लेके चल रहा हूँ
00:48:21कहां से कहा है
00:48:220 से 4
00:48:23battery नहीं लगाई तो kinetic energy की range
00:48:260 से 4 maximum है 4
00:48:29minimum है 0
00:48:30अब मैंने 2 volt के battery लगई
00:48:32ये 2 volt के battery के कारण ये प्लस बना ये माइनस
00:48:37electric field
00:48:38force
00:48:39force के कारण kinetic energy दराई
00:48:42अच्छा क्या यहां से यहां पर
00:48:44potential difference
00:48:462 का आगया 2 volt पर
00:48:48तो 2 के कारण
00:48:492 के potential difference के कारण
00:48:52जो काई ने जिदर आएगी
00:48:53वो 2 EV और
00:48:56आजाएगी
00:48:57maximum पहले किती थी चार दो रोगई 6
00:49:02minimum 0 प्लस दो दो
00:49:04अब एलेक्ट्रों के काईनेटिक एनर्जी
00:49:06minimum 2 और maximum 6 हो जाएगी
00:49:09ये सुझ में आएगा
00:49:11बहुत आसान चीज है बस सुन लिए तो सब आजाएगा
00:49:14साहाब मैक्सम क्योश्य तो ये एक्सरसाइस रोके
00:49:16मैक्सम तो ऐसे सॉलो होंगे टिक
00:49:17लेकिन बस पता हो ना जो काईनेटिक एनर्जी कैसे आती है
00:49:200 से 4 थी जब बैटरी नहीं लगई
00:49:23अब बैटरी तुमने 2 वोल्ट की
00:49:243 माल लो अभी 4 वोल्ट की लगा थी
00:49:264 वोल्ट तो यहाँ पोटेंशल डिफरेंस
00:49:28चार और यहाँ 0 तो पोटेंशल डिफरेंस
00:49:31चार खा पोटेंशल डिफरेंस
00:49:33इलेक्ट्रिक फिल्ड एलेक्ट्रिक फिल्ड के करण
00:49:35पोर्स पोर्स के करण चला
00:49:37चला तो काईनेटिक एनर्जी आई
00:49:39काईनेटिक एनर्जी की वैल्यू
00:49:41charge charge ki value
00:49:42e into
00:49:454 volt
00:49:464 volt
00:49:474 electron volt
00:49:494 electron volt
00:49:504 electron volt
00:49:50इधर और आ गया
00:49:52पहले 0 से 4 था
00:49:534 सब को extra मिला
00:49:55तो maximum हो जाएगा
00:49:578 minimum हो जाएगा
00:49:580 plus 4
00:49:59यह चीज़ के लिए
00:50:01तो यह ऐसे बढ़ जाता है
00:50:02बैटरी लगाने पर
00:50:04अचा मैंने अगर इसको
00:50:056 volt की बैटरी लगाई होगी
00:50:07तो maximum 10 हुआ होगा
00:50:09और minimum 6 हुआ होगा
00:50:10अचा अब मैंने देखा
00:50:126 volt की बैटरी के बाद
00:50:14अगर मैं 7 volt लगा रहा हूँ न
00:50:15तो electron
00:50:17current में कोई फरक नहीं पड़ा
00:50:18हाँ 7 volt लगाऊँगा
00:50:21तो electron की kinetic energy
00:50:2311 होगी maximum
00:50:24minimum 7 हो गई
00:50:27लेकिन जितने electron थे
00:50:29वो तो पहले 6 पर ही पहुच गए थे
00:50:31तो electron के current current
00:50:33electron के numbers change नहीं हुए तो current में कोई फरक
00:50:35नहीं ही पड़ा लेकिन kinetic energy तो बढ़ रही है
00:50:37मैं बैटरी इतनी बढ़ा हूँगा
00:50:39current maximum हो चुका है
00:50:41अब मेरे दिमाग में कुछ आया कि कुछ खुराफात करें
00:50:43अच्छा photo electric तो हो चुका है
00:50:45मतलब electron निकले हैं और circuit में घूम गया है
00:50:48और current आगया तो photo electric effect हो गया है
00:50:50अब कुछ खुराफात आई है कि देखते हैं कुछ उल्टा सोसते हैं
00:50:54ये सही काम नहीं है
00:50:56लेकिन हाँ
00:50:57ये experiment के अंदर नहीं innovation है
00:51:00कि ऐसा कर लिख करके topic और strong हो जाता है
00:51:02किसी ने बोला बैट्री उल्टा करो
00:51:04जरूरी है नहीं करना
00:51:06वो करवा रहा हो
00:51:07क्योशन में अप्रोच बनाएगा कि ऐसा कर दो तो क्या होगा
00:51:10अगर मैंने बैट्री उल्टी कर दिया
00:51:26प्रोच बन गया अब यह हाई
00:51:32पोटेंशल यह लोग पोटेंशल
00:51:34अरे लाइट अभी भी इस पर गिर रही है
00:51:36इलेक्ट्रों तो अभी भी निकल रहे है
00:51:39तो चाहे तुम बैट्री उल्टा करो
00:51:40चाहे सीधा करो अरे इसकी
00:51:43अगर वर फंक्शन से ज्यादा होगा
00:51:45तो अलेक्ट्रों निकलना है तो निकलना ही है
00:51:46तो अलेक्ट्रों निकल जाएगा
00:51:48अच्छा इसकी जगह इस पर इलेक्ट्रों गिराते तो
00:51:50इसकी जगह इस पर फोक्रों गिराते तो
00:51:53to be other only energies camera functions a jada was the electron tonically data photo
00:52:00electron emission to own a ita and a possible row here many key a minus or a key a plus battery
00:52:06come out of a point of human a plus charge or minus charge about a electron either take on the
00:52:13charge of my electron minus or your minus K minus is going to tell career but of anime he
00:52:19to take a share do satirica a plus okay top electric up high potential low potential a potential difference
00:52:27in her electric field potential different that electric field me either electric field
00:52:34cake current electron per force either so joelette putters are at a war ruka jaya items really
00:52:41do so jayen get to zero all it a tonic I know it takes the zero all it a unpeto jam for
00:52:48like the other is this the only thing that it is the only thing that it is the only thing that it is
00:52:54the only thing that it is the only thing that I can't ask it maximum kinetic energy can't be
00:53:004
00:53:02if I am going to stop it
00:53:04then I will be able to stop it
00:53:08so I will be able to get the battery
00:53:11that will be 4 volts
00:53:14if I am going to stop it
00:53:17then I will be able to get the battery
00:53:20opposite direction
00:53:214 electron volts
00:53:22kinetic energy
00:53:23when I am going to stop it
00:53:25maximum kinetic energy
00:53:264
00:53:26then I will stop it
00:53:29।
00:53:59It is not what we can do, but it is not what we can do.
00:54:26do say I got Charvala team said sub electron nairo care abhi be current I
00:54:32got my name is for the world cardia to do a little bit of the link in Pino Charvala
00:54:38Neuroke my name is for team cardia team weller get Charvala Charvala Neuroka to
00:54:43go current abu lara come lara lekin lara lekin jesse minutes for child
00:54:48I got a top Charvala Biroka subro get subro get a current zero
00:54:53which is the battery which is supposed to be placed in the circuit, which will stop the current in the circuit.
00:55:00The current will stop the maximum kinetic energy.
00:55:04That battery means stopping potential.
00:55:08Stopping potential means the potential in which we will stop.
00:55:12Listen to the ultigation.
00:55:14I have 10 electron volts.
00:55:18This is 4 electron volts.
00:55:22How much is it?
00:55:240-6.
00:55:266-2-3-3.
00:55:29I have to stop the current.
00:55:31Ulti battery.
00:55:326-6.
00:55:34Stopping potential means 6 volts.
00:55:37It is simple.
00:55:39Take this diagram.
00:55:41Current.
00:55:42It will stop the current.

00:55:50.
00:55:51Aь, but, current, that's a rise.
00:55:54Current.
00:55:55Current.
00:55:56But, that's a mass.
00:55:57Current.
00:55:58Current.
00:55:59Current.
00:56:00Yes, it will come, but we have to stop the current, which is the definition of maximum current.
00:56:13Yes.
00:56:16And then we will go through the current.
00:56:18Yes.
00:56:19Then we will go through the current.
00:56:21Then we will go through the current.
00:56:23Then we will go through the current.
00:56:25Yes.
00:56:26Yes.
00:56:27Yes.
00:56:28Yes.
00:56:29Yes.
00:56:30Thank you, sir.
00:56:32Yes.
00:56:34Well, I do not see the current.
00:56:37Yes.
00:56:38Right.
00:56:39Yes.
00:56:41Yes.
00:56:42Yes.
00:56:44Yes.
00:56:45Yes.
00:56:49Yes.
00:56:50Yes.

00:56:52Yes.
00:56:53Yes.
00:56:54When?
00:56:55I will just listen to you.

00:59:16Pahala point, this diagram is what we have to do first.
00:59:26Even at VAC equals to 0, sum of photoelectrons even at VAC,
00:59:42VCA or VAC is 0, sum of photoelectrons bracket of maximum kinetic energy
01:00:02will reach to anode,
01:00:12and current appear in circuit.
01:00:24Second point, if VCA is further increased,
01:00:32if VCA is further increased,
01:00:37more electrons will complete circuit,
01:00:46and current increases up to its maximum value,
01:01:04and current increases up to its maximum value.
01:01:16In the bracket saturation current,
01:01:19in the bracket saturation current,
01:01:23in the bracket saturation current,
01:01:25if polarity of battery is reversed,
01:01:32if polarity of battery is reversed,
01:01:36if polarity of battery is reversed,
01:01:48if polarity of battery is reversed,
01:01:52then current starts decreasing.
01:02:04the certain value of potential
01:02:28in opposite polarity at which current in circuit becomes 0,
01:02:47becomes 0,
01:02:54for which current in circuit becomes 0,
01:02:57is known as,
01:02:59is known as stopping potential.
01:03:060.
01:03:09Stopping potential
01:03:14V O,
01:03:15V will be potential
01:03:16New will be potential
01:03:17V capital
01:03:19O,
01:03:20or Vs.
01:03:21stopping potential.
01:03:23So, what is the stopping potential in the cathode and renault?
01:03:36In the emitter and collector, which is the stopping potential?
01:03:44So, what is the stopping potential?
01:04:02Next, the maximum kinetic energy, which is the electron?
01:04:13That is E into VO.
01:04:20Yes, I am telling you.
01:04:37So, let's see how it is.
01:04:39How we have written it?
01:04:41Kinetic energy is Q into V.
01:04:44This is what we have written.
01:04:46Dimensionally correct.
01:04:47We have maximum kinetic energy, which is 4.
01:04:50If I have 4, which is how much?
01:04:54Battery is 4.
01:04:564 volts into E.
01:04:594 electron volts.
01:05:00This is maximum kinetic energy.
01:05:02So, this is the electron's kinetic energy.
01:05:05But, what is it?
01:05:07What is the battery?
01:05:08The current is the electron.
01:05:09The electron is put together.
01:05:11So, this is the example.
01:05:13Energy has 12 volts.
01:05:15Work function has 4 volts.
01:05:17Work function has 4 electron volts.
01:05:20So, what is kinetic energy?
01:05:22What is the photo electrons?
01:05:23How much is it?
01:05:240 to 8 electron volts.
01:05:28This will be 0 to 8 electron volts.
01:05:29This will be 0 to 8 electron volts.
01:05:33So, if you ask me,
01:05:34No.
01:05:35You have to stop the potential.
01:05:37So, what should I do?
01:05:39What should I do in the ultidirection?
01:05:41What should I do in the ultidirection?
01:05:42How much?
01:05:438.
01:05:448 volts.
01:05:458 volts.
01:05:468 volts.
01:05:478 volts.
01:05:488 volts.
01:05:499 volts.
01:05:509 volts.
01:05:51Is it going to go out and go out?
01:06:21I am going to tell you what I am going to tell you about it.
01:06:45I am going to tell you what I am going to tell you about it.
01:06:47This is the current that we are talking about in the circuit and this is the current that we have connected to the battery.
01:06:56How much is the current here? How much is the voltage here? 0.
01:07:00How much is the voltage here? If the voltage is positive here, then we are doing the battery.
01:07:08This is positive and this is negative.
01:07:12First of all, we have written a point that when the value of VCA is 0, then there is a current.
01:07:20Why is the current?
01:07:21If it is 0, then the maximum kinetic energy will still be reached.
01:07:25When it is 0, then there is a current.
01:07:28But if you have the battery of 1 or 2 volts, then you will not be able to increase.
01:07:34But it will increase the fixed value.
01:07:37After that, this is constant.
01:07:40Some of the currents are constant.
01:07:41Well, it's such aomination.
01:07:43So, this was the current current.
01:07:45Matte, what does this mean?
01:07:46ItsCu
01:07:47What time is this moment?
01:07:53a four photon download or photon download it or electronic link a number of electrons
01:07:59because they are not a number of photos but on a number of photos but on a putting about
01:08:04love intensity but I need to get intensity as a body this dance come care care but the
01:08:11source plate kept us later I'm a better tell now would last get points I think it's zero
01:08:17so current I have to say that as I am going to the maximum kinetic energy how much I have
01:08:24added one voltage so one one is stopped but now three two three and four are running
01:08:30so current but one is finished so current is a little bit less than two and more than three
01:08:37and more than three and more than everything is finished so which voltage is put on the
01:08:42So, when you see a graph, you can see the stopping potential.
01:08:49And if you see a graph, you can see the stopping potential.
01:08:52And if you see the stopping potential, you can see the maximum.
01:08:58If you listen to a question, we have a metal that works function is 3 electron volts.
01:09:11We have the metal that works for 3 electron volts.
01:09:17I have the metal that works for 3 electron volts.
01:09:22I have the current that comes to the stopping potential is 4 volts.
01:09:28The stopping potential is 4 volts.
01:09:31If I put 4 volts on the battery, I will stop.
01:09:36If I put 4 electrons in the body, I will stop.
01:09:39If it will stop, there will be 4 electrons.
01:09:41If I put an electron to the bottom, the number later in the chair goes,
01:09:45there will be a 4 electron wave.
01:09:47So, it will stop until 4 volts.
01:09:49So, there will be more results from the body.
01:09:50If you see the energy of which 4, then it will stop so far away from 4 of the object.
01:09:54energy 7 kiya hai, wavelength incident kye puchta kata, 12,400 upon lambda equals to 7,
01:09:59yya lambda a gya, yya ulta, ulta bhi question a bantay hai, ki verbal resolve one
01:10:03wane waale questions te, picture clear hai, toh sab clear hai, thik hai, isko banao.
01:10:24Stopping potential 4 hai, mtlap ulta battery 4 volt ki lagai hai,
01:10:30aur us per current ho gaya ho ga zero, 4 volt ki lagane hai, pere koon sa wala electron ruk gaya ho ga?
01:10:374 electron volt hala, woi yya sapsa maximum tha, toh mtlap 4 electron wala hai, bhi ruk gaya ho ga,
01:10:44yya ni ki maximum kinetic energy 4 tha, stopping potential work function kitna tha? 3,
01:10:50toh aya kitna ho ga? 7, 7 mai se 3, aur yya 4, toh 4 wala ke liye 4 ki ulta bhi tlap lagai hai.
01:11:00Lekh liya hai?

01:11:51You
01:11:51Yaha par
01:11:52Sab ke liye kya same
01:11:54is shown.
01:11:56For example,
01:11:58we have a problem here.
01:12:00For all of us.
01:12:04Stopping potential is the same.
01:12:06You can understand.
01:12:08Stopping potential is the same.
01:12:10The same is the same.
01:12:12The same is the same.
01:12:14The maximum kinetic energy
01:12:16is the same.
01:12:18This means that
01:12:19the maximum kinetic energy
01:12:22is the same.
01:12:24Is it the same?
01:12:26We have three
01:12:27อันimeterals around here.
01:12:32Karena사람
01:12:33because of
01:12:34metal yser
01:12:35work function
01:12:36is the same.
01:12:40It's the same.
01:12:41This random clue
01:12:42the incident photon
01:12:43can be again.
01:12:47Worani
01:12:49Rating
01:12:50frequency
01:12:51HAVE
01:12:52So we have to make this first case, this second and third case.
01:12:55In the first case, the frequency of the second and third case,
01:12:58all the same will be the same.
01:12:59So we will go back to the point of the point.
01:13:01If we have the first three graphs of a metal on the first case,
01:13:06then the light of the same frequency of the same.
01:13:08The light of the same is the same.
01:13:10So the same is the same.
01:13:14And the metal of work function is fixed.
01:13:16So if it is 6, 6, 6 and this is 2,
01:13:20so 6 minus 2, 4.
01:13:22So we have maximum kinetic energy, 4 is.
01:13:25And so we have stopping potential is the same.
01:13:29But we have saturation current.
01:13:34Saturation current is the same.
01:13:37So we have electron.
01:13:39So because saturation current is different,
01:13:43this means number of electrons is different.
01:13:48And if the number of electrons is different,
01:13:51this means number of photons is different.
01:13:56Because if the photon is different,
01:13:58the photon is different.
01:13:59So the photon is different,
01:14:02the incident light intensity is different.
01:14:06To make it moreximately different.
01:14:10So we can press the first,
01:14:11and we can press them ult.
01:14:12These momentum integrates
01:14:34I proportional to capital I for fixed mu.
01:14:48If you look at this value, the value of N, H, new by A.
01:14:55If we have this value fixed, the amount of photon, the amount of electron will be the current.
01:15:07The value of N, H, new by A.
