I am a high school Physics teacher, and have had this question for some time:
In an electromagnetic wave are the two fields in phase (both sine
function) or out of phase (one sine and one cosine)?  Every book I have
consulted shows E and B in phase, but this doesn't make sense if the
derivative of the electric field gives the magnetic field (Faraday's Law).
What's the deal?
