Have viewed PF, first time post (have searched for this question on forum):
The energy of EM radiation can be described by the Poynting vector S = E x B (insert conversion factor for cgs, MKS, etc).
For a traveling EM wave, what happens to the instantaneous value of S when E and B are max as compared to when E and B are 0?
Alternatively, how is the energy of the EM radiation shared between E and B with both E and B having maximum and zero values at the same instant of time for a plane wave?
Thank you for your input.
