In a plane electromagnetic wave propagating in space has an electric field of amplitude

9 \times {10^3}\mathrm{\;V}{\mathrm{m}^{ - 1}}

, then the amplitude of the magnetic field is

View answer and explanation

Correct option: D

3.0 \times {10^{ - 5}}\mathrm{\;T}

Option D (

3.0 \times {10^{ - 5}}{\;\mathrm{T}}

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