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?

View answer and explanation

Correct option: B

153\mathrm{ }N{C^{ - 1}}

Option B (

153{\;N}{C^{ - 1}}

) is correct because the amplitude of the electric field is calculated by multiplying the magnetic field amplitude by the speed of light.
