Which of the following is a characteristic of an electromagnetic wave? a. it travels at the speed of light b. it can be transverse or longitudinal c. it involves displacing a medium in the same direction the wave moves d. it requires a medium to travel through

The answer should be A. It travels at the speed of light

A.It travels at the speed of light

Explanation:

Electromagnetic waves are the waves that are produced by an electromagnetic field carrying electromagnetic radiant energy. Electromagnetic waves travel at the speed of light.

It can only be a transverse wave.

It does not involve displacing a medium in the same direction the wave moves so it does not require a medium to travel through.
