I'm not sure where to ask this question or if it even makes sense...
Say an electromagnetic wave passes through a point in space. The point experiences some fluctuation of electric and magnetic fields. But what happens after the wave has passed? Are there any lingering effects, like a "wake" of some kind, or does the wave leave absolutely no evidence of its having been there?
