That's what I initially thought,
But my teacher as well as the solution to the question asked in the entrance all seemed to disagree.
But I satisfied myself by the argument I gave here https://www.physicsforums.com/threads/power-of-a-thin-lens-in-a-medium-is-1-f-or-m-f.1082649/#post-7285050
Well that did give me the answer.
Thanks a lot.
I was still not happy as to why the 'power' which I feel is a property of lens alone must depend on
μ in addition to the fact that power depends on focal length which itself depends on μ.
Power is essentially a measure of how much a lens can...
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that...
