1. Electromagnetic waves have a fixed relation between the electric and magnetic fields E, B, and the direction of wave propagation k. The figure shows three cases where two of the three vectors are shown. In each case the vectors shown are either perpendicular to the paper, or lie completely in the plane of the paper. a) For each case, draw the third vector. a) E B B
