Question

If the electric field of an electromagnetic wave is in the x-direction and the magnetic field of the wave is in the y-direction, the wave is traveling in the:__________.

a- z-direction.
b- x-direction.
c- y-direction.
d- xy-plane.
e- z-direction.

Answer 1

Positive z-direction

Step-by-step explanation:

According to Fleming's right hand rule, point the fingers of your right hand in the direction of Electric field E ( positive x-direction), and curl your fingers toward magnetic field B (positive y-direction), and your thumb points in the direction of propagation of wave (positive z-direction).

Therefore, the correct option will be positive z-direction.
