B Photons -- do you know what they are?

  1. Apr 14, 2017 #1
    Does anybody know what a photon is? Light used to be known as electromagnetic wave till 1900, but then it's particle was made justified by photoelectric effect, Compton effect. And we know about diffraction, interference, etc. And it has no mass.

    You should do a forum search. "What is a photon" has been asked many times.
