Electromagnetic Waves

The ratio of the contributions made by the electric field and magnetic field components to the intensity of an electromagnetic wave is ( $c$ = speed of electromagnetic waves):

A. $c : 1$
B. $1 : 1$ ✓
C. $1 : c$
D. $1 : c^{2}$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
