Electromagnetic Waves

  1. Oct 5, 2008 #1
    For an electromagnetic wave, why is the electric field in phase with the magnetic field? As one increases in a given positive direction, so does the other (also in a given positive direction). I was somewhat expecting them to be slightly out of phase for some reason.

    If its not too much to ask...can anyone provide a post showing the mathematics for deriving electromagnetic wave phenomenon from Maxwell's equations...sort of looking for them

    who says they are in phase?

    I see...so they are not necessarily in phase...could you clarify (or provide the math)?
