Exactly how is the energy being transfered to the sphere if all the light passes through the hemisphere? Also what should be the approach to this?

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.hmm ping me when you get ans
also can you send the question
could they be simply referring to energy / vol in hemisphere
glass hemishphere is solid or hollow?
I presume solid.
i assume
when light changes mediums
lamda also changes
that will change momentum , Lmada = h/p
change in momentum = force
Ah. Nice catch.
Will try to move on from here.
ye i try too
Wait, in the energy momenta equation E=p.c, does c refer to speed of light in that medium or the speed of light in vacuum?
idk
ye no clue on how to move forward
if u get another lead tell
speed of light toh is like same in all medium

*Effective speed.
Use E = h(nu)
The c is going to be the speed in vacuum, not in medium.
Ah, but then there is no energy loss in the question, so where does the power go?
Oh mb i just gave the energy stored.
I didn't see the whole question
