I was reading now that photons when created are already at light speed, they don't accelerate. That's because they are in this instance a wave, and a wave is a distortion of its medium; the whole wave can instantly be created at a certain speed (for example throw a rock into a pond, the waves will immediately radiate at speed). So in reverse then, when absorbed the wave could be cancelled out and it is forced into particle behaviour?
