Does the exact same photon of light bounce back or is it absorbed and a new one with the same properties emitted? how does it remember its path? And if it bounces back, does its velocity comes to near zero for a small-time before being reflected back in a straight line at same angle.
In: Physics
The individual wavefunctions corresponding to the photon interacting with each particle in a perfect mirror are in superposition. They only constructively interfere along the path where the angle of incidence is equal to the angle of reflection.
