Sinusoidal Wave

The amplitude...

Question

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

Open in App

Solution

$B_{0} = 510 \times 10^{- 9} T$
$C = 3 \times 10^{8} m / s$
$E = c B_{o} = 153 N / C$
