2:25:50 opposite angle sum is not equal to 180 in every case...it was 180 because rest 2 angles were 90 (normals) therefore 360-90-90= A + N, therefore A + N = 180

Mam I think in 6:10 :-Concave mirror: silver polished outside of the surface of sphere not inside :- Convex: silver polished inside the surface of the hollow sphere not outside..... Please reply mam Am I right?
The reason I was waiting for this video is actually to check something about refracting telescopes and here it is finally! Thank you mam for your effort 🫰🫰 I was anxious if I will be able to watch this before the next Friday and now I'm completely satisfied. ᕙ(`▽´)ᕗ - An old student of yours
Double-Convex lens are to be manufactured from a glass of refractive index 1.55 with both faces of the same radius of curvature. What is the radius of curvature required if the focal length is to be 20cm Ans:- R=40
Mam, please post the one-shot video of electromagnetic waves as well. Only that chapter is left. Please, mam. We are waiting for your videos. Those who want a video on that chapter, either like this comment or comment the same thing yourself so that it may reach mam.
thank you ma'am for the amazing lesson, this really helped for upcoming ISC physics exam held on 17th may. it very much informative and interesting video ☺️
More legends starting physics...After wasting whole 8 months and giving statement yarr pata hi nahi chala saal kaise bit gaya..Corona ke bad kuch toh gadbad hua hai 😂
Mam plz revise full wave optics in live class.. so that our concepts should become crystal clear ❤ Plz inform us before starting wave optics so that we all should come on time.
1:14:41 the condition of the total internal reflection is that the light rays should be travel from denser to rarer medium but in practically she passed the light ray from rarer to denser ....it means total internal reflection can be occured without that one condition
Thank you so much ma'am for all your efforts. It'd be great if you could upload the one shot videos of *Wave Optics and Semiconductor* *before* the other chapters cause they are a bit lengthy and consumes time to understand. ❤❤ Grateful to you
Mam in concave mirror silvered coating is in outer side of spherical and in canvex the coating is in inner side ?????? If u am wrong then plz tell me and u do some mistake then clear my problem mam plzzz i am too confused🙏🏻
Exactly bro I also thought the same, but mam made a mistake ,silvered side is actually the outer side of concave mirror and vice versa... sometimes mam also make Lil mistakes but it's okay
Thank you mam for creating physics one shot 😊😊😍🙇🙇 amazing and experiments you are doing is superb 👌👌 and phir toh concept clear hona hi h 😁😁 thank you mam 😘
Extentionally. Thankful 🥰🥰Ma'am ur teaching way is amazing❤️❤️i am getting every points all the points which is in ncert ..I suggest to my friends to see your video nd shares ur link to my friends for a better knowledge which is given by you ....love uh ma'am ❣️for this much ....
The main thing which i like about you guys is that you start from the basics of a chapter which is a good thing. Thank u LearnoHub team for bringing wonderful contents😊😊
Thanks mam because my all concepts are crystal clear.... When i in 10th standard, I hate optics but after seen in video my concepts clear and my interests also generate.again thanks so much..................!!!

For those unable to recall triangle law I have an alternative 02:22:08 method to prove delta=angle 1+ angle 2
First let's take the 3rd angle of triangle MQR be angle 3
now we know straight line 180°
angle delta + angle 3= 180°
Angle 3 = 180 - angle delta ...(1)
Now in triangle MQR we have angle 1+angle 2+angle 3 =180° (because all angles of triangle=180°)
Now angle 1+angle 2+180° - angle delta = 180° {from ...(1)}
Now angle 1+angle 2 - angle delta = 180°-180°
Angle 1+angle 2=angle delta
And hence proved

Then 1/u = 0 and v = f and 1/V = 1/f

Results?

Thank you mam ❣️❣️
Very nice explanation..!😍
1:14:00 That total internal reflection example with glass of water was spot on!
44:17 focal length of concave mirror = -ve
Convex lens = +ve?

Ray Optics and Optical Instruments
Refraction (delete only advanced sunrise and delayed sunset), Mirage, Diamond, Some Natural Phenomena due to Sunlight, The Rainbow, Scattering of Light {deleted topics} for boards 2023-2024
This is far far better than Offline coaching ❤❤❤❤❤❤❤❤❤❤❤
Haan yaar
Mam I think in 6:10
:-Concave mirror: silver polished outside of the surface of sphere not inside
:- Convex: silver polished inside the surface of the hollow sphere not outside.....
Please reply mam
Am I right?
Watching 3 days before and doing 1 chapter with this chapter
My my all journey of class 12 starts with you and end with you 🎉 thankuuu🎉

In quadrilateral AQNR, sum of all interior angles is 360°
i.e, A + AQN + QNR + ARN = 360°
( Normal = AQN = ARN = 90° )
Thus, A + QRN = 180°
Who is watching for 2025🥶

I am complete this lecture in two days with so much fun with crystals clear 💖 Bohot Mja aaya Mam ke sath ray optics padhke Aab wave optics bacha he👍👍
In lens makers formula can u plz explain why we take 1/f in place of n1/f ? 😅

Thank you so much mam for this wonderful one shot💗✨
For CBSE Term 2....
The syllabus starts from 52:14
Skip that part that you know......
Thank me Later.....
Amazingly easy. Very nice efforts didi. God bless you.
The reason I was waiting for this video is actually to check something about refracting telescopes and here it is finally! Thank you mam for your effort 🫰🫰 I was anxious if I will be able to watch this before the next Friday and now I'm completely satisfied. ᕙ(`▽´)ᕗ
- An old student of yours
That's the toughest topic.same i was also looking for this..even microscope and telescope consists 1 ques of three marks
Bro is these videos are enough for nest exam ( competitive exams)?
Double-Convex lens are to be manufactured from a glass of refractive index 1.55 with both faces of the same radius of curvature. What is the radius of curvature required if the focal length is to be 20cm
Ans:- R=40
Thankyou for making the toughest lesson of physics term 2 easier 🙏🏻
Can you pls provide time stamp...where term 2 is starting?

Is it enough for bards exams
no
ma'am at 15:42 the diagram for concave should be corrected; the ray is not passing through focus..
the incident ray
2:40:19 phle refraction hua red aur violet ka phir reflection phir refraction jab reflection hua tab refraction kyu nhi hua
Tabhi saala science nhi lena tha
2023 batch present lagao jo physics ke paper ke liye padh rahe hai 😳👇👇👇❤️😊😊😂😂

Mam, please post the one-shot video of electromagnetic waves as well. Only that chapter is left. Please, mam. We are waiting for your videos.
Those who want a video on that chapter, either like this comment or comment the same thing yourself so that it may reach mam.
2:12:35 why we will be using thin lens formula and not mirror equation formula

thank you🥰🥰🥰🥰
46:00 min question 1 me magnification wrong h -2 nhi 2 hoga human mistake appreciated the lecture ❤
More legends starting physics...After wasting whole 8 months and giving statement yarr pata hi nahi chala saal kaise bit gaya..Corona ke bad kuch toh gadbad hua hai 😂
True😂😂😂
Mam plz revise full wave optics in live class.. so that our concepts should become crystal clear ❤ Plz inform us before starting wave optics so that we all should come on time.
1:14:41 the condition of the total internal reflection is that the light rays should be travel from denser to rarer medium but in practically she passed the light ray from rarer to denser ....it means total internal reflection can be occured without that one condition
She is wrong
For 2024-25 students,
Deleted topics from ncert are:
1. Refraction(advanced sunrise/sunset)
2. Mirage,Diamond
3. Natural phenomenon(sunlight)
4. Rainbow
5. Scattering of light
eye??
i think there is a mistake at 43:38 in concave mirror LHS f is -ve
Haa -ve aayega
Also a mistake in TIR derivation..
Thank you so much ma'am for all your efforts. It'd be great if you could upload the one shot videos of *Wave Optics and Semiconductor* *before* the other chapters cause they are a bit lengthy and consumes time to understand. ❤❤ Grateful to you
Please ma'am 🙏🙏
Wonderful so crystal clear lecture understand everything very easily❤❤❤

41:51 in the diagram on the right hand side it is meant to be positive and not negative. much obliged
Mam in concave mirror silvered coating is in outer side of spherical and in canvex the coating is in inner side ?????? If u am wrong then plz tell me and u do some mistake then clear my problem mam plzzz i am too confused🙏🏻
Hi
Exactly bro I also thought the same, but mam made a mistake ,silvered side is actually the outer side of concave mirror and vice versa... sometimes mam also make Lil mistakes but it's okay
Thank you mam for creating physics one shot 😊😊😍🙇🙇 amazing and experiments you are doing is superb 👌👌 and phir toh concept clear hona hi h 😁😁 thank you mam 😘
