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? - Bill Cambre {ihnp4!}mtuxo!45223wc P.S.: I just know my kid is going to ask me these questions some day.
