A plane electromagnetic wave of frequency 20 MHz travels through space along the x-direction. If the electric field vector at a certain point in space is 6 V m-1, what is the magnetic field vector at that point?

Question

A plane electromagnetic wave of frequency 20 MHz travels through space along the x-direction. If the electric field vector at a certain point in space is 6 V m^-1, what is the magnetic field vector at that point?

$2 \times 10^{-8} \, \text{T}$

$\frac{1}{2} \times 10^{-8} \, \text{T}$

$2 \, \text{T}$

$\frac{1}{2} \, \text{T}$
