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?

also can you send the question

could they be simply referring to energy / vol in hemisphere

glass hemishphere is solid or hollow?

SirLancelotDuLacOP•4/25/25, 3:37 AM

I presume solid.

SSirLancelotDuLac I presume solid.

Gamertug•4/25/25, 3:38 AM

i assume

Gamertug•4/25/25, 3:38 AM

when light changes mediums

Gamertug•4/25/25, 3:38 AM

lamda also changes

Gamertug•4/25/25, 3:38 AM

that will change momentum , Lmada = h/p

Gamertug•4/25/25, 3:38 AM

change in momentum = force

SirLancelotDuLacOP•4/25/25, 3:39 AM

Ah. Nice catch.

SirLancelotDuLacOP•4/25/25, 3:39 AM

Will try to move on from here.

Gamertug•4/25/25, 3:39 AM

ye i try too

SirLancelotDuLacOP•4/25/25, 3:40 AM

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?

Gamertug•4/25/25, 3:42 AM

idk

speed of light toh is like same in all medium
