Quizplus · Accepted Answer

The direction of propagation of an electromagnetic wave is given by the cross-product of the E-vector and B-vector. In this case, since E is in the +z direction and B is in the +x direction, their cross-product will be in the +y direction. Therefore, the direction of propagation of the electromagnetic waves is in the +y direction.
