B and E are typically illustrated in a symmetric phase shifted oversimplified sine wave(s). Are the B and E waves ever non-symmetrical to one another? This seems to make no sense to me, as they induce one another. Also EM waves do not always involve the release of photons, correct? I was once told the easiest way to make a Electromagnetic wave was to comb your hair(get a charge on comb), then wave the comb up and down. By definition this movement of charge generates an Electomagnetic wave, no photons released here as charge moves up and down, correct? Thanks for any clarification!
