In a vacuum, the plane wave solutions to Maxwell's Equations are...
E=E0*cos(wt-kr)
B=B0*cos(wt-kr)
ie they are in phase. (See for example

Can someone please tell me the name of the theory describing the interaction of photons with charged particles eg electrons, protons?
Can you also suggest a good introductory web page describing that theory at First Year University level for self study? Better still, a good VIDEO lecture on...
1. So, if the universe is closed, there would seem to be no point in talking about monopoles. We could just talk about gigantic magnets?
2. And if the Universe is not closed, presumably one pole could move so far away from us that a light signal couldn't reach us from it (because of the...
Still Puzzled!
1. Wouldn't this mean that there are as many north monopoles as there are south monopoles? In other words they come in pairs?
2. Suppose then there were just two monopoles in the (multi)universe, wouldn't this mean that the field would look identical to that of a (gigantic)...
It was sometime ago so I don't recall the exact video. I did attempt to watch the early Cosmology Lectures by Leonard Susskind so it was probably mentioned in one of those. Sorry, I can't be more specific.
