Hey /sci/.
What are the physical properties that determine whether or not a photon will be reflected, absorbed or ignored when directed at an object of mass?

Also, there are mirrors for photons from the visible part of spectrum. Can there be mirrors for gamma rays, or thermal waves?

Is this a typical homework question, since there are no answers?

This was never mentioned in my courses.

why can't you just google it?
yes, it's a standard homework problem, it's just that nobody cares about you
there is a stupid question thread, people will answer it in there

>Can there be mirrors for gamma rays
surface
pretty hard since
a) gamma rays deeply penetrate material
b) scattering xrays will greatly change their energy
look up
>>compton effect
>>(de)coherence
also more general
>>reflection law

should point you in the right direction

>or thermal waves?
pretty much anything we got on this planet - think about it
