00:02:13.
00:02:21And you can see here.
00:02:24You can see 50 cm from the slab.
00:02:28The slab is 15.
00:02:31You can ask what you can tell.
00:02:34What you can tell? Shift.
00:02:37Can you see the pin or the upper one?
00:02:41How can you see the coin?
00:02:44Now shift.
00:02:45D, 1-1 by D, 15.
00:02:53Mu, 1.5, 3, 2, 2.
00:03:04Maje ki baat ye hai.
00:03:07Is 50 cm ka.
00:03:12No use.

00:04:58?
00:05:00?
00:05:02?
00:05:02?
00:05:04?
00:05:04?
00:05:04?
00:05:04?
00:05:04?
00:05:05Red.
00:05:08Is it okay?
00:05:10Let's go.
00:05:12The other thing is 5.
00:05:16The question is, it's a question in class notes.
00:05:18You can make it in class notes.
00:05:22You can write it in class notes.
00:05:24It's just DPP number 2, post number 5.
00:05:28Copy it, it's a question.
00:05:31DPP maintain, folder,
00:05:34which is systematic,
00:05:36which is the best way to go.
00:05:38Which is the best way to go,
00:05:40which is the best way to go.
00:05:47DPP number 2,
00:05:505.
00:05:52A light race traveling from air to glass.
00:05:58Air from glass.
00:06:00The reflected and refracted.
00:06:06This is air from glass.
00:06:10Now he said,
00:06:12reflected.
00:06:14So you have to reflect.
00:06:16Reflect.
00:06:18Reflect.
00:06:20Reflect.
00:06:21Reflect.
00:06:22Reflect.
00:06:23Reflect.
00:06:24Reflect.
00:06:25Reflect.
00:06:26Reflect.
00:06:27Reflect.
00:06:28Reflect.
00:06:29Reflect.
00:06:30Reflect.
00:06:31And both are.
00:06:33Perpendicular to each other.
00:06:35Find out.
00:06:36Find out the refractive index of glass.
00:06:41Reflect.
00:06:42Reflect.
00:06:44Reflect.
00:06:45Reflect.
00:06:46Now that's how really,
00:06:47it's hard.
00:06:48One of the things.
00:06:49We will find out the world.
00:06:51Every place.
00:06:53It's all prepared.
00:06:54One of the things,
00:06:56three concepts will be born.
00:06:58Three,
00:06:59three,
00:07:00three,
00:07:01four.
00:07:02This is more important for all
00:07:03our emotions.
00:07:04this is the eye, can this also be the eye?
00:07:08The first concept is angle of incidence
00:07:12with angle of reflection.
00:07:16This is the eye.
00:07:20The second concept is the eye.
00:07:24The straight line on all the angles
00:07:28of the eye.
00:07:3290
00:07:34R

00:07:42I plus R
00:07:4490
00:07:46R
00:07:4890 minus I
00:07:50The first concept says
00:07:52angle of incidence
00:07:54with angle of reflection
00:07:56The second
00:07:58straight line on all the angles
00:08:00angle of the angle

00:45:03Oh, yeah.
00:45:06Oh, yeah.
00:45:10Diagram, I need.
00:45:13So, if you set the critical angle on the critical angle, then how much degree will be refraction? 90.
00:45:24Set the critical angle on the critical angle on the critical angle on the critical angle.
00:45:34Critical angle is an standing angle on the Carolективan angle of the main Meanwhile, which means Cortopardy's critical angle on the critical angle on the critical angle.

00:46:42This is the first formula which we have given in NCRT.
00:46:47Critical angle, sin Theta C, 1 by Mu.
00:46:53But it is not necessary, brother.
00:46:57Every time the other side will be here.
00:46:59Yes, this is necessary, it should be rarer.
00:47:03But it is not written here, that if something is possible, something can happen.
00:47:11So, in the past, we have another chitra.
00:47:14Snell losses, we can be able to do it.
00:47:21This is not written here, that if the other side will be rarer, it will be rarer.

00:50:01There are some lots of money,
00:50:04people can't1't get in their life,
00:50:09when the price add in the price.
00:50:14..oh say the what doesn't this cost?
00:50:19We say sign value again..
00:50:20Come on the value..
00:50:25Sign of stating which except left,

00:51:07this, why is it true? Why is it true? You know, if it's true, if it's true, when it's true?
00:51:14You know, it's true. If it's true, you know, there is a value. Where will you go?
00:51:19Where will you go? Where will you go? Where will you go? When will you go?
00:51:24Yeah, when will you go to lambda? If you go to lambda, I will not know what to do.

01:08:52یہاں پہ کوئی mirror.
01:08:55یہی تو important ہے.
01:08:56ایسا لگ رہا ہے.
01:08:57جیسے کوئی mirror کی طرح کام کر رہا ہے.
01:08:59جبکہ یہاں کوئی mirror تھوڑی نہ ہے.
01:09:01light کیا ہو گئی.
01:09:03angle critical سے کیا ہو گیا.
01:09:05جیسے کوئی mirror.

01:09:16نیچے.
01:09:17واپس پانی میں آنے لگ گئی.
01:09:20اسے بولتے ہیں.
01:09:21circle of vision.
01:09:24اگر آپ باہر سے دیکھو گے pond کو.
01:09:26imagine کرو.
01:09:27pond ہے.
01:09:28آپ باہر سے دیکھ رہے ہیں.
01:09:29تو پتہ ہے آپ کو pond میں سے.
01:09:32جو پرکاش باہر آتا ہو دکھ رہا ہے.
01:09:34وہ کس کے روپ میں دکھے گا.
01:09:36کیوں circle کیوں.
01:09:38یہ دو point یہاں دکھ رہے ہیں.
01:09:39یہ دو ادھر توڑی نہ.
01:09:40ادھر بھی ہے.
01:09:41ادھر بھی ہے.
01:09:42پیچھے بھی ہے.
01:09:43پیچھے بھی ہے.
01:09:44تو پورا کیا بنے گا ایک.
01:09:45circle.
01:09:46that's where topic کا نام کیا ہے.
01:09:49circle of vision.
01:09:51سر اب ایک بات دیرے دیرے بتائیے.
01:09:53پھر سنیے.
01:09:53ایک ایک step.
01:09:55imagination کو لائیے.
01:09:56pond.
01:09:58تالاب میں پانی بھرا ہوا ہے.
01:10:00تالاب کے اندر.
01:10:02bulb.
01:10:02bulb سے.
01:10:03پرکاش نکل رہا ہے.
01:10:05imagine کریے.
01:10:06آپ تالاب کے اندر ہیں.
01:10:08آپ torch لے کے.
01:10:09ایسے ایسے.
01:10:10light کو باہر پھیک رہے ہیں.
01:10:11جب آپ نے ایسے پھیکا.
01:10:13یہ دیکھیں.
01:10:13light کہاں چلی گئی.
01:10:14ہوا میں.
01:10:15light کہاں چلی گئی.
01:10:16ہوا میں.
01:10:17سر یہ کیا ہو رہا ہے.
01:10:18یہ bending کیوں بھڑ رہی ہے.
01:10:20کیونکہ angle کیا ہوتا جا رہا ہے.
01:10:21بھڑتا.
01:10:22پہلے آپ نے ایسے پھیکی.
01:10:23پھر آپ نے ایسے پھیکی.
01:10:25angle کیا ہو رہا ہے.
01:10:26بھڑ رہا ہے.
01:10:26bending.
01:10:27بھڑ رہی ہے.
01:10:28یہ دیکھیں.
01:10:28پہلا diagram آج کا.
01:10:30یہ دیکھیں.
01:10:31پہلا diagram.
01:10:33یہ دیکھیں.
01:10:34light ایسے تھی.
01:10:35پھر ایسے گئی.
01:10:36پھر ایسے گئی.
01:10:37پھر نبھے پہ گئی.
01:10:38اور اس کے بعد.
01:10:39واپس نیچے آگئی.
01:10:41ایسا لگ رہا ہے.
01:10:43کہ light.
01:10:44light.
01:10:45واپس.
01:10:46کہاں چکی ہے.
01:10:47نیچے.
01:10:48جبکہ وہاں کوئی mirror.
01:10:50نہیں ہے.
01:10:51وہاں کوئی پتھر بھی.
01:10:52نہیں ہے.
01:10:53مطلب light نے کیا کر دیا.
01:10:55T.I.R.
01:10:56بتائیے.
01:10:58کیا.
01:10:58کیا.
01:10:59کیول پرکاش.
01:11:01اس circle سے ہی بہار نجر آئے گا.
01:11:03کیا.
01:11:05کیا.
01:11:05اس circle سے ہی بہار نجر آئے گا.
01:11:07کیا.
01:11:08کیوں.
01:11:09اس کے بعد کیا ہو رہا ہے.
01:11:10اس کے بعد کیا ہو رہا ہے.
01:11:12T.I.R.
01:11:13اب یہ والی light.
01:11:15بہار نہیں جائے گی.
01:11:16ٹکرا ٹکرا کے کہاں آئے گی.
01:11:18نیچے.
01:11:20اور اس circle کی جو radius ہے.
01:11:23اس radius کو ہی بولتے ہیں.
01:11:25radius of visibility.
01:11:28اور بولیں circle of vision.
01:11:31اور اس کا جو فارملا ہوتا ہے.
01:11:33وہ آپ سبھی کو یاد بھی ہے.
01:11:35R برابر.
01:11:36H upon.
01:11:38under root.
01:11:39mu square minus 1.
01:11:43سنیل لوس اس کو ڈرائیو کر سکتے ہیں.
01:11:45پر ڈیریویشن کی آویشکتہ نہیں ہے.
01:11:47board exam دینا نہیں ہے.
01:11:48تو سیدھا ہمیں یاد ہونا چاہیے.

01:14:48R کا فرملا بتائیے.
01:14:49H upon mu square minus 1.
01:14:52دھیان دینا.
01:14:54اوپر air ہے.
01:14:56اس کو بھی start لگا لینا.
01:14:58ایک بار ایٹی میں سوال آیا بھی.
01:14:59میں نے مائنر میں بھی دیا تھا.
01:15:01اوپر میڈیم تھا.
01:15:03تو کیا لگانا پڑے گا.
01:15:05کالا جادو.
01:15:07بتاؤ کیسے.
01:15:08دونوں طرف ڈیوائٹ کر دوگے.
01:15:11یہ بات دیاماک میں بیٹھاؤ.
01:15:13کہ یہ جو فرملا آپ ڈیرائیو کر رہے ہو.
01:15:16جہادہ تر.
01:15:17NCRT نے دوسری طرف کیا مانا ہے.
01:15:20air.
01:15:21کیا بات OK ہے کیا.
01:15:24آگے بڑھیں.
01:15:26دیکھ لیجئے.

01:15:33mu کیا ہے mu.
01:15:35refractive index.
01:15:39بڑھوں آگے.
01:15:41چلیے.
01:15:43اسی میں لکھتے ہیں.
01:15:44اگلا ایک question لکھتے ہیں.
