An electromagnetic wave of frequency 1×1014 Hz is propagating along z – InterviewSolution

1.	An electromagnetic wave of frequency 1×1014 Hz is propagating along z-axis. The amplitude of electric field is 4 V/m. If ϵ0=8.8×10−12 C2/N-m2, then the average energy density of electric field will be,
Answer» An electromagnetic wave of frequency $1 \times 10^{14} Hz$ is propagating along z-axis. The amplitude of electric field is $4 V/m$ . If $ϵ_{0} = 8.8 \times 10^{- 12} C^{2} {/N-m}^{2}$ , then the average energy density of electric field will be,
