8.7 The amplitude of the magnetic field part of a harmonic electromagnetic wave in vacuum is $B_{0} = 510 nT$ . What is the amplitude of the electric field part of the wave?

Hint: $c=\frac{E_{0}}{B_{0}}$
Step 1: Find the amplitude of the electric field of an electromagnetic wave.
The amplitude of the magnetic field, $B_{0}$ $T$
Speed of light in a vacuum is given by, c = $10^{8}$
