Geometrical Optics | Advanced Problem | Displacement of Image Due to Rotation Of Lens

Monochromatic light rays parallel to the principal axis (the x axis) are incident on a convex lens of focal
length f. If the lens oscillates such that it tilts up to a small angle θ on either side of the y axis, then find the distance between the extreme positions of the image. Take secθ=1+ θ^2/2 for small θ. Advanced problems Playlist

Thank you very much sir

Sir Thanks A LOT !!!! I was looking for the exact same question for the past 3 days. Thanks a lot for the amazing explanation

[Arnold-qlnv]

Thank you sir, I had doubt in this question, bcoz this came in one of the Jee main grand test conducted by my coaching. Now I understood clearly.

Finally can sleep peacefully thank u sir was waitin sir

Sir, How can we find velocity of image at any general time(INTERMEDIATE position of lens to be precise)?

[beluga]

Good evening sir, I had a query. Kindly guide me here. I am a dropper, had a rank of 14k in adv last year(2020). I improved somewhat this year and got 99.4 in jee mains, (only saw your lectures, so much credit goes to you). Now I cannot decide how to approach these two months. The dpps given by resonance( my institute) is not at all of 2020 level. I decided to finish all your advanced problem playlist once, but then some questions feel too too difficult and I feel I'm wasting time. I know that my IQ level is such that I can secure a 4000 rank at best . Keeping that in mind.sir please please tell me what I should do next. Given my aptitude etc, should I do pathfinder level 1 or what must I do.

Why can't we use equation of refraction two times????

[ishaanagarwal]

So, it is better if we remember that if rays are tilted by an angle, then the new image is formed in focal plane. Sir, Is this valid only for small angles?
