Questions and Answers

Electromagnetic radiation consists of waves of the electric field only, and does not involve the magnetic field.

False

Electromagnetic radiation travels at a speed denoted by the symbol c.

True

The position of an electromagnetic wave within the electromagnetic spectrum can be characterized by either its frequency or its wavelength.
