If there was a way to see the electromagnetic waves that is all around us, i.e. see the electric and magnetic fields spreading away from an antenna say, how would it look? I mean if we were to freeze the picture to a single instant of time, and somehow construct a 3D diagram of the spreading electromagnetic disturbance how would it look.
Considering that in nature, a change in electric flux creates a change in magnetic flux and vice versa and they sustain each other as they spread out, how would the picture look? starting from a single circle of electric field, would it create infinite circles of magnetic field perpendicular to itself around its circular periphery and those magnetic fields in turn give rise to infinite circular electric fields around themselves? This is a poor explanation possibly but the point is just how the EM wave propagates and how it looks like in reality?
