A photon is massless, has no electric charge, and is a stable particle. In a vacuum, a photon has three possible polarization states. The photon is the gauge boson for electromagnetism, and therefore all other quantum numbers of the photon (such as lepton number, baryon number, and flavour quantum numbers) are zero. Also, the photon obeys Bose–Einstein statistics, and not Fermi-Dirac s… WebNov 10, 2015 · It does require a little more computation, using properties of the operators and matrix mechanics, but in general it is not the case that a photon has an orbital …
