Take a normal pane of window glass and a photon somewhere within the visible range.
My limited understanding is that when light passes through glass one shouldn't think of little spheres travelling through the glass but must take into consideration quantum effects which somehow give a kind of statistical average resulting in the photons seeming to pass through the glass like little spheres.
What would happen if one photon propagated through the glass?
It wouldn't have the presence of all the other photons to reach some kind of average.
Direction of reflection and refraction can be predicted when large numbers of photons are involved.
I don't think the resulting direction could be predicted with one photon.
I imagine it would be absorbed by the first electron it meets and then re-emitted in a random direction.
Any better understanding on what would happen here?
