Particle Man and the Photon

When a photon ( a very small increment of energy) encounters a substance one of three things may happen. (1) The photon may be transmitted -- it passes through without alteration. (2) The photon may be absorbed -- the photon never leaves the particle. (3) The photon may be scattered -- it's path may be altered.
