Although mass-less, a photon, like any other quantum particle, has a frequency/wavelength associated with its energy/momentum. If we have a group of photons all with the same specific energy, then each photon can be represented by a little, complex-valued plane wave. Photons are also EM waves and, as such, have (I assume) little Electric and Magnetic sine waves. How are those electric and magnetic (classical) wave components related to the above complex-valued plane waves? Thanks in advance.
