i have never ever seen a physics teacher like u in my whole life. u r legend sir and thank u so much sir for being a good explainer and giving us free education thanks a lot.
close to tears right now i was so scared of this chapter, because a tuition teacher taught me this chapter in such a way that I hated physics. he skipped the basics, scolded me for not getting it at one go and always picked at how I wont pass 10th at my pace. but pw, explained it so simply, and so beautifully that I'm proud of myself for finishing this chapter. and it wasn't that hard either. hats off to you this foundation. saving lives.
57:05 n = c/v v = c/n There fore, speed of light in : A = c/1.33 B = c/1.50 C = c/1.52 D = c/2.40 It shows that the speed of light in medium A is maximum and in medium D is minimum. So, when light travels from any of these mediums to medium A, speed will be maximum and when light travels from any of these mediums to medium D, speed will be minimum
Homework Question: (i) Change in the speed of light will be minimum when the change in refractive index will be minimum.. Therefore, when travel from B to C or C to B it will experience minimum change in its speed due to minimum change in refractive indices of the mediums. (ii) Change in the speed of light will be maximum when the change in refractive index will be maximum.. Therefore, when travel from A to D or D to A it will experience maximum change in its speed due to maximum change in refractive indices of the mediums. Majaa aagya sirji !!!😁
Right bro me bhi yahi soch raha tha but i think sir ne question galat padh liya...wo speed of light ko maximum ya minimum soch rahe the but question me "change in speed of light" pucha hai....but glad to see ki tumne bhi sahi answer diya hai... goodluck 👍
the best physics teacher ever found. I don't know why my school can not have a teacher like this although my school is very good but then also after completing the chapter from the school i have to again do it at home.
Yrr I have the same teacher or best teachers as him in my school whereas that's not too expensive ,and fee is also tolerable ...I am glad to study here..
velocity of speed in medium is inversely proportional to the refractive index therefore, velocity will be maximum in the first case{ a} and will be minimum in the last case{d}
Best channel and best teacher with a very detailed vdo.... I got to learn more than the ncert text book.... I recently started studying on this channel.... It's too helpful.... Thank you so much to all the teachers here...❣️
55:42 Answer:- Speed of light is minimum in (A) Maximum in D Because As we know that,Refractive index is inversely proportional to the speed of light.Hence if refractive index is more then change in speed of light is maximum and if the refractive index is less then change in speed of light is minimum....

Answer of last question, Minimum - When light travels from A to D(since A and D has maximum difference in R.I.) Maximum - When light travels from B to C(since B and C has least difference in R.I.)
Sir It was seriously unbelievable that my all doubts got cleared Sir I am extremely thankful for your efforts and the team as well. It is genuinely straight from the heart. Sir sach mai maza aa gya
Change in speed will be minimum when light will travel from B to C or C to B as change in their refractive indices is minimum similarly change in speed will be maximum as light travels from D to A or A to D as change in their refractive indices is maximum (you can also think if light light goes from vaccum to air there will be negligible change in speed as change in their refractive indices is negligible)
20:24 sir said right but there is one more thing is that if you add all power than you also find the power let us assume the total power of the lens is 20D P=1/F 20=1/F F=1/20 .05 meter(5 cm)
56:01 light will travel the fastest in medium A and slowest in medium D as velocity of light in a medium is indirectly prototional to the refractive index of that medium
