# Trying to understand EM wave and photon

When electrical fields and magnetic fields couple together, it forms electromagnetic waves. And we can "quantized" it and see each "package" of it as photon. So can electrical fields and magnetic fields be each "quantized" and visualized as a particle (half a photon?)

this is worth reading motls.blogspot.gr/2011/11/… –  anna v May 15 '13 at 13:34

we can in a way "quantize" the separate fields - How can this be done? Could you provide any reference to a QED textbook? –  firtree May 14 '13 at 16:50
