Physics - EM Waves Question with Solution | TestHub

In a plane EM wave, the electric field oscillates sinusoidally at a frequency of$5\times {10}^{10} \mathrm{Hz}$and an amplitude of$50 \mathrm{V} {\mathrm{m}}^{–1}$. The total average energy density of the electromagnetic field of the wave is : [Use${\epsilon }_0=8.85\times {10}^{–12} {\mathrm{C}}^2 {\mathrm{N}}^{-1} {\mathrm{m}}^{-2}$]
