C)+y direction
D)-z direction
E)+z direction

Question

Quizplus · Accepted Answer

The direction of wave propagation in an electromagnetic wave can be determined using the right-hand rule, where the thumb points in the direction of the electric field (E), the index finger in the direction of the magnetic field (B), and the middle finger in the direction of wave propagation (S). Given E is in the -z direction and B is in the +y direction, the wave must be traveling in the +x direction.
