My understanding of EM wave emission on a particle level is that when an electron jumps to a lower energy level it emits a photon. The probability of where you will find this photon is described by a wave, so when you have a lot of photons you are safe to treat light as a wave (in most circumstances). Radios work under frequency modulation or amplutude modulation. Say for amplutude modulation the frequency is constant and the strenght of the EM wave is varied. Does this mean on an emmission level the atoms in the metal are simultanously emitting a large amount of photons one microsecond then not as many photons the next microsecond. I am confused as to what goes on inside an antenna when a signal is transmitted.
