What's a photon?
What happens when two photons hit each other?
Do photons lose energy when they bounce off things?
Do photons lose more energy when they bounce off black things
than when they bounce off white things?
How about mirrors?
If I have a hollow sphere with a mirror coating on the inside
and a light source in it, and say the light cannot get out of the
inside of the sphere, if I leave the light source on for a while,
will the sphere fill up with photons?  Will it get full?
Will it get brighter and brighter in there?  If I keep the light on
in there for  30 years then suddenly break open the sphere, will
I be blinded by all the light that explodes out of it?

What's the difference between photons in a red light and photons in a
blue light.  I thought red and blue light are energy in a certain
wavelength.  Does a photon have a wavelength?

Does anybody really know?

P.S.: I just know my kid is going to ask me these questions some day.
