To start with I would personally describe a photon as a single EM wave of any frequency. Secondly, do I understand you correctly with regard to QED. Are you saying that photons travel at the speed of light in all medium until they interact with a charge particle at which point, I assume they...

I would argue that it is still a photon when traveling through a medium, for example I can still see using light when standing the in the medium of air or water. Also you state that “obviously the common mass of the media and photon remain constant”, why would this obviously be the case, since...

Several sources, including these two http://strathprints.strath.ac.uk/26871/5/AbMinPRL.pdf, http://www.hep.princeton.edu/~mcdonald/examples/abraham.pdf.

I know that a photon has no mass when it is traveling at the speed of light, however my question is, can a photon have mass when traveling through a medium, i.e. when its speed is less than c? I have done some reading but cannot find an answer. From this reading I have got the following: We...
