The ratio of average electric energy density and total average energy density of electromagnetic wave is :

Accepted Answer

Avg electric energy density

=\frac{1}{4} \varepsilon_0 \mathrm{E}_0^2

Total Avg energy density

=\frac{1}{2} \varepsilon_0 \mathrm{E}_0^2

∴

Ratio of average electric energy density and total Avg energy density

= \frac{\frac{1}{4} ε_{0} E_{0}^{2}}{\frac{1}{2} ε_{0} E_{0}^{2}} = \frac{2}{4} = \frac{1}{2}
