In an answer to a another question, the poster states without sources the following:
From a quantum mechanical perspective, all light scattering is a form of absorption and re-emission of light energy. Photons don't bounce off a surface.
If this is true, what is the evidence for it, or is it a theoretical postulate under quantum mechanics?
The reason I ask this is that the statement would seem to be contradicted by the phenomena of specular reflection. Since specular reflections always faithfully reproduce the spectrum of the incident light, that would suggest that no light is be absorbed and that, indeed, photons are "bouncing" off of the surface.
