Question

A linearly-polarized sinusoidal electromagnetic wave propagates in the –x direction. At a particular moment in time, the magnetic field at point (–4, 0, 0) points in the –z direction. At that same moment at (–4, 0, 0), what is the direction of the electric field? Drawing a diagram should help. Group of answer choices –z direction +z direction +y direction –y direction

Answer #1

Consider that the electric field is pointed along
.

Then
X (-
) = -

X
=

For this relation to be correct,
=

So, the direction of electric field is along **+y
direction**.
