Question:
I read somewhere that the photon has three spin states, but since it travels at the speed of light the t, the transverse state does not exist. Why is this?



Replies:
A partial response...The photon only has the transverse polarization of the electric and magnetic fields. If these are what are called circularly polarized (the electric vector spins either clockwise or counter-clockwise around the direction of travel) then the "spin" is along the direction of travel. In this sense the transverse spin state of the photon does not exist.
