Question

as an electromagnetic wave travels, what is the relationship between the magnetic field and the electric field along its path? a. the angle between them decreases with an increase in energy. b. they are at a 90° angle to each other. c. they are parallel to each other. d. the angle between them increases with an increase in energy.

Explanation:

Electromagnetic waves are transverse waves where the electric field and the magnetic field are perpendicular to each other and also perpendicular to the direction of wave propagation. This is a fundamental property of electromagnetic waves and is not related to the energy - the orientation of the fields relative to each other remains constant.

Answer:

B. They are at a 90° angle to each other.
