Question

question 18 of 25
how are the oscillating magnetic and electric fields of an electromagnetic wave positioned relative to each other?
a. they are parallel to each other.
b. the magnetic field is rotated 45° from the electric field.
c. they are perpendicular to each other.
d. the electric field is rotated 45° from the magnetic field.

Explanation:

In an electromagnetic wave, the oscillating electric field and the oscillating magnetic field are oriented such that they are perpendicular to each other and also perpendicular to the direction of wave - propagation. This is a fundamental property of electromagnetic waves.

Answer:

C. They are perpendicular to each other.
