00:00:00How about this?
00:00:06How about this?
00:00:24We have seen this in the last class, we have seen Ray Optics in the portion of the screen, first of all, we have talked about light.
00:00:31Light, what is it? EM Wave. EM Wave is just light, or something else?
00:00:36Gamma, X-ray, Ultra Wallet, Visible, Inferent, Micro Radio, what is it? EM Wave.
00:00:41Light, which is the range of 4,000 to 7,800.
00:00:47It is not just the range will be a higher, and it will consist of the lens, the lens, the lens, the lens, the lens, the lens, the lens, the lens, the lens.
00:01:07So this is the wavelength, it is not straight, it is ray.
00:01:13ray optics slits के लिए way optics उसके बाद में हमने बात किया था यार यह दो
00:01:19medium को separate करने वाली boundary यहाँ पर एक जगह से light आई जहां
00:01:23से light आएगी source अच्छे इसको बोलेता है incident ray पहला काम
00:01:28normal angle हमेशा normal से incident का angle angle of incident क्या incident
00:01:36होगा यहाँ पर कौन से incidents होंगे light गिर रही है क्या हो सकता है
00:01:41reflection भी हो सकता है और reflection भी हो सकता है अच्छा लेकिन
00:01:47silvering कर देंगे तो यह वाला पार्ट नहीं होगा ऊपर होने के चांस है लेकिन
00:01:52ideal silvering real life में possible नहीं है ती आई यार का मतलब total internal
00:01:57reflection light जो भी गिरेगी वो पूरा का पूरा ही अपने आप reflect होगा यहाँ
00:02:04पर यह अच्छा यह एंगल क्या किलाता है आई ही होता है जितने एंगल पर है उतने पर जाएगा यह वाला
00:02:09angle angle of reflection light की जो speed होती है वीकोल्स टू एल लैम्डा एंड किस पर
00:02:15डिपेंड करता है सोर्स पे जब तक यह सोर्स चेंज नहीं होगा यह फ्रिक्वेंसी एंड एंड और यह एंड कलर के बार हम बोलते के प्रिक्वेंसी एंड माल लो यह वाइट कलर आ रहा है तो वाइट कलर क्या कोड़िंग इसकी एक
00:02:34पानी में चल जाए तो भी रेट कलर रएट ही रहेगा हा लेकर यार एक चीज तो फिक्स है फ्रिक्वेंसी से में लेगे अलग मीडियम में जाने पर इस पीड अलग और अगर स्पीड अलग तो वेव्लेंद भी अलग यह कैसे
00:02:54and it has become more or less than the problem with the main place.
00:03:03To decide, optical density means that light is not like the danger of which minimal distance
00:03:16optical density and class 11
00:03:18mass density
00:03:20mass upon volume
00:03:22the mass density
00:03:24and optical density
00:03:26light
00:03:28medium is rare
00:03:30or dancer
00:03:32mu
00:03:34mu value is
00:03:36c by v
00:03:38medium
00:03:40c to come
00:03:42constant
00:03:44mu
00:03:46zada to medium dancer
00:03:48dancer to v
00:03:50v kam to lambda b
00:03:52so we have mu wavelength
00:03:54and this is a relation
00:03:56this is clear
00:03:58this is clear
00:04:00this was the last class

00:07:54or vacuum go a medium month and look in other polarize light vacuum say medium
00:07:58matter vacuum say air major a so for same money illegal a cushion
00:08:04mandra a light air say funny major a funny dancer a cushion man right
00:08:10vacuum say glass major a glass dancer the great one right it's a vacuum
00:08:16major a air and otherwise air vacuum same again other one made of the right

00:30:39then
00:30:41This is the value of mu into sin theta.
00:30:47If you want one to two, mu is increasing, then sin theta and sin theta is less than that.
00:30:57The sin of sin theta is less than that.

00:50:15so you can see Hitler oh yeah okay but can't say that era is a medium new man
00:50:23new but I come over a concept new key value can't say that he won't say new new key value
00:50:33takes a body of you new but I speed the wavelength angle
00:50:39Aare one say mu
00:50:46में जा रहा है
00:50:47mu बढ़ गया
00:50:49sine theta कम होगा
00:50:52sine theta कम होगा
00:50:53यानि कि angle कम होगा
00:50:55angle कम होगा यानि कि light
00:50:57normal की तरफ मोड़ेगी
00:50:59यह जो चीजे बता ही थी वही चल दिए
00:51:01जो जहांसे सुन रहा होगा उस्ता काम बन रहा हो
00:51:03incidence कौन कौन से होगे
00:51:08phenomenon
00:51:08phenomenon मतलब जो भी तक पढ़े है
00:51:13reflection या reflection
00:51:16दोनों होने तो दोनों है
00:51:20mirror थोड़ी न है दोनो
00:51:22if reflected ray
00:51:24if reflected
00:51:29reflection
00:51:30reflected ray
00:51:31and refracted
00:51:34and
00:51:35refracted
00:51:37refraction भी ओर है
00:51:38reflected ray and refracted ray
00:51:41becomes perpendicular to each other
00:51:43reflected ray and refracted ray
00:51:49becomes perpendicular to each other
00:51:52then find out value of mu
00:51:58then find out value of mu
00:51:58then find out value of
00:52:10angle of incidence
00:52:14angle of incidence
00:52:20diagram बनाये जो कह रहा है वो करें क्या पता पहुच जाए है हमारे answer तक
00:52:26question में
00:52:27कौन सी एक value दी हुई है
00:52:30mu
00:52:33तो answer भी किस form में हैगा
00:52:35mu के form
00:52:36सोचें
00:52:39गल्टी होगी
00:52:40कोई उम्मीदे नहीं है
00:52:41कर लोगे नहीं करोगे
00:52:42समसे हम सोचे नहीं होगे
00:53:12कर दो
00:56:42Okay.
00:56:44Take care.

01:00:52This is just the same thing and the same thing is not the same thing.
01:00:56So, water and glass is the same thing for me, I will keep it in the same way.
01:01:01But glass has a different quality.
01:01:04Different material, different glass, different glass, different type of transparent, non-transparent, soundproof.
01:01:11All the refractive index is different.
01:01:13Optical density is different.
01:01:15There will be some light.
01:01:16There will be some light.
01:01:23There will be some light.
01:01:25So, if I can see what I can see, I can see what I can see.
01:01:29But I can see what I can see.
01:01:32So, what I can see here is glass.
01:01:35Here is water.
01:01:37Here is water.
01:01:39This is the difference.
01:01:42Here is water.

01:05:32Okay.
01:05:47Okay.
01:05:54I am a class that I'm only the pillar
01:05:58I am going to talk about it
01:06:01I am going to talk about it
01:06:03I am going to talk about it
01:06:05Homework ELP 1
01:06:08Is that right?
01:06:11Exercise 1
01:06:14Reoptics exercise 1
01:06:1625-30
01:06:20Do you have any questions?
01:06:24Do you have any doubts?
01:06:26No
01:06:28If it happens again
01:06:30If it happens again
01:06:32If it happens again
01:06:34If it happens again
01:06:36These are two things
01:06:38ELP 1
01:06:40I am going to talk about it
01:06:42I am going to talk about ELP 1
01:06:44I am going to talk about it
01:06:46We are going to talk about it
01:06:48I am going to talk about it
01:06:50I am going to talk about it
01:06:52We are going to talk about it
01:06:54So, what is it?
01:06:56No
01:06:58It's not
01:07:00Not
01:07:02It's not
01:07:04It's not
01:07:06This one, this one, this one, and the rest of us, I'm going to die.
01:07:11When I was online, I was a big group, I was going to die.
01:07:25First, I'm going to see the solution, then I'm going to see the solution.
01:07:31The condition of normal incidence.
01:07:45This one, I'm going to see the solution.
01:07:52Normal, we have one medium, two mediums.
01:07:59Light, this one, this one.
01:08:04First, what do we do?
01:08:07Normal.
01:08:08Now, this is normal.
01:08:09But the incident rate is normal?
01:08:11We speak normal incidence.
01:08:14If I become normal incidence,
01:08:18if I become normal,
01:08:19this incident rate is the same.
01:08:22Normal, the surface is perpendicular,
01:08:25the surface is perpendicular,
01:08:26this incident is the same.
