First Question: What process happens when things absorb light ? Like something that is black for instance, or something that is red or green, (abosorbing all of the different wavelengths of light except the red or green ones) - What does it mean to absorb the light / photons ? Where do they go ?
Second Question: White light, is it single photons of white light containing the whole of the visible spectrum of wavelengths in a single quanta. OR is it that the photons are of ALL different wavelengths are bombarding your eyes; and you percieve them to be white as they would be travelling too quickly and in such numbers that your brain is not quick enough to differentiate between each one ?
Third Question: Can photon's bump into each other ? What happens when they do ?
Fourth Question: Standing anywhere in what appears to be an "empty space" somewhere in the cosmos (pick any or loads of random spots to stand) and you will see stars; you will see the light of stars; does this mean that in effect; doesnt matter where you are, there will ALWAYS be a photon there ?
