In a plane electromagnetic wave, the magnetic field oscillates sinusoidally at a frequency of $2.0×10^{10} Hz$ and amplitude $1.6×10^{-7}T$. The amplitude of the oscillating electric field is:

$48Vm^{-1}$

The correct answer is Option (4) → $48Vm^{-1}$

The relationship between $\vec E_0$ and $\vec B_0$ is,

$E_0=CB_0$

$E_0=(3×10^8)×(1.6×10^{-7})$

$=48Vm^{-1}$
