Question

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

Answer 1

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

Answer 2

A.It travels at the speed of light

Step-by-step 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.
