Most of them are. But if a photon collides with an atom, it is absorbed and raises the energy level of the atom. When the energy level of that (or any) atom decreases, the energy difference is emitted as one or more photons. Its direction will be unrelated to the direction of any incoming photon.

The idea of the 'photon' was put forward to explain a few of the properties of light but in most cases it behaves as a mixture of waves. The waves pass through most well ordered structures with usually only a small amount being absorbed. If it were a photon it would be more difficult to explain how coloured filters work or why light 'bends' when it passes from one material to another at an angle.

As far as I know a photon is not a particle or (particle as waves) but a (fast frequency mass vibration due say to the rotation of electrons rotating around an atom nucleus in this case a silicon atom) So in this case it must have lost energy but is still a perfect copy of is former self...
its a vibration like sound

Yep, photons can do odd things but just like the you reading this is the same you who asked this can't change their identity!

Yes, they do not change when doing what you said.
