Sir it's my 2nd time that I'm solving all 32 questions and I have solved all this questions and understanding all the points because of only the help of your revision vedio thank you sir
for ones who are confused with the approach of question 37:27, here's how I went about doing the question: we know for TIR, i>c sin i> sin c here i=45 degrees (from diagram) sin45> sinc but we know sinc=1/n 1/root2>1/n n>root2 i.e n>1.414 which means that for TIR, refractive index should be greater than 1.414. Here blue and green lights obey this condition. So they will be reflected internally, whereas red will emerge

39:58 Sir this question can be dealt with an easier approach. Lets assume that the angle of prism is 90 degrees. So, deviation = 90(n-1) after calculating the deviation of all the three rays, we can infer that red deviates the least and blue deviates the most. Jyada se jyada red aur green deviate kar sakta tha, but there is no option like that so our best possible answer would be red.
28:00 q4 - dispersive power. Really challenging and tough 32:00 q5 good question got struck in finding R 36:49 q- 6 why won't we use lens maker formula as it's not mentioned that it's a lens. 47:00 tricky question. Do again 58:00 q8 good question 1:06:00 q2 really good question

Sir I have one request sir, i know this is physics channel , but i am having lot of problem with thermodynamics of chemistry, if you could make a 1hr session discussing all the similarities and differences it will be a great help🙏🏿. I am sure many students are facing these problems.

for ones who are confused with the approach of question 37:27, here's how I went about doing the question:
we know for TIR,
i>c
sin i> sin c
here i=45 degrees (from diagram)
sin45> sinc
but we know sinc=1/n
1/root2>1/n
n>root2
i.e n>1.414
which means that for TIR, refractive index should be greater than 1.414. Here blue and green lights obey this condition. So they will be reflected internally, whereas red will emerge

39:58 Sir this question can be dealt with an easier approach.
Lets assume that the angle of prism is 90 degrees.
So, deviation = 90(n-1)
after calculating the deviation of all the three rays, we can infer that red deviates the least and blue deviates the most.
Jyada se jyada red aur green deviate kar sakta tha, but there is no option like that so our best possible answer would be red.

excellent dear
57:13 sir in question 7
Can we use optical cable formula that is: i=sin-1 √Ud²-Ur²
I wish we had eduniti for chem and maths as well as ❤😂😊
Love love love lots of love from madhyapradesh sir❤❤❤

33:00 good question
best content for physics channel
Sir I'm able to solve 20-21 questions by myself.🙂

1:23:40 sir but hame to padaya gaya hai ki agar object syemetry par hoga tabhi Image 2 bange ....... so answer is right ?🤔🤔🤔

well done on completing it
keep learning and solving
Really, you are the best sir! 🙏🙏🙏
keep learning
Sir at 1:05:00 focal length is given in cm , so how u put it in the eqn although we have to find velocity of image in m/s
Plz clarify ki mai kaha galat samajh rhi hu ,I know Mai hi galat samajh rhi houngi
😅 Sir ne jaha value put kiya hai waha quantities ratio me hai actually... U can put it in meters usse koi frk nhi pdega Qki vo cut ho jayega & answer same hi aayega 👍🏻
charan sparsh guru ji.................. ( how to thank you sir)
stay blessed
just keep learning and growing
Mohit sir 👑
Sir, agar q2(Feb attempt) mein object 2f par ho jaye toh bhi same size ka image banaya?
Thank you so much sir this really helps me to clear all concepts by practice questions through your vedio thanks sir ❤
application of concepts understood ab ek bar khudse karunga
well done dear

Sir I have one request sir, i know this is physics channel , but i am having lot of problem with thermodynamics of chemistry, if you could make a 1hr session discussing all the similarities and differences it will be a great help🙏🏿. I am sure many students are facing these problems.
bhai bas sign convention hee to diff hai baaki saare concepts to same hain
search video of shantanu sir on this
Same to h sub
Onlu differ work done sign
@@mahabirsaharan3830 no entropy bhi hai and reversible me kaam karta hai chemistry it's bit different but mains ke liye suffice ho sakta
Done this session also enjoyed it, ty mohit sir☺️❤️
Keep it up
25:00 new variety
Out of syllabus bro😅
15:22 but nowhere in the question it is given that the line will divide mirror into two equal halfs. Please reply 🙏🏻🙏🏻
Sir plss check at 1:17:50 object is placed at focus so its image will formed at infinity ♾️ then 🤔
that is in case of convex lens dear.
Ok sir 👍
46:00 sir ye to cheating hai 🤕🤕🤣 maine dono ka ri alg maan k solve kra aap aise jldi kr loge
sir in question 2 why we don't use displacement method??....because it is also used to find focal length of convex mirror
D is distance between screen and object. Screen kaise pata kroge. Dono Mai same size ka image banrha hai. V same nahi h. Bs height of image same h
