Electric fields generate magnetic fields and visa/versa,and this is attributed to be how a light ray self propagates. Can anyone further clarify how exactly light rays self propagate? If the mechanism is comprised of these two components, wouldn't the machanism have to be instantanious given the frequency of the wave is so high? /visible light is the portion of the EM spectrum of interest/ Aside from the above citation of the fields generatating each other, both components would have to be present at the photon's emission unless one comes first and generates the other, in which case the components would be out of phase ? Can anyone shed some light for me please.
