If individual photons were absorbed and re-emitted, glass would not be transparent to them. |
Not true, this is exactly how photons travel through a piece of glass.
Try these.
French (French.A.P. 1968a Special relativity (p128. Nelson. London)) states “the propagation of light through a medium (even a transparent one) involves a continual process of absorption of the incident light and its reemission as secondary radiation by the medium.” Feynman (Feynman.R.”Q.E.D.- the strange story of light and matter”.P76.
Penguin.London.1990.) describes the transmission of light through a transparent medium simply as “photons do nothing but go from one electron to another, and reflection and transmission are really the result of an electron picking up a photon, ”scratching its head”, so to speak, and emitting a new photon.”
This is not in doubt.
