MCQ+4 / -12024
In a plane EM wave, the electric field oscillates sinusoidally at a frequency of \(5 \times 10^{10} \mathrm{~Hz}\) and an amplitude of \(50 \mathrm{~Vm}^{-1}\). The total average energy density of the electromagnetic field of the wave is : [Use \(\varepsilon_0=8.85 \times 10^{-12} \mathrm{C}^2 / \mathrm{Nm}^2\) ]
