## Main Question or Discussion Point

Can we imagine electro-magnetic field in vakuum as a massless particle that respects

Klein-Gordon equation (instead of Electromagnetic wave equation)?

It seems to me that both equations are the same, except that the electro-magnetic field can have 2 possible polarizations (then we count them as 2 different particles?).
