Question

$E=E_0 \sin (\omega t-k x)$

Energy density $\left(\frac{d u}{d v}\right)=\varepsilon_0 E_0^2 \sin ^2(\omega t-k x)$

$\frac{\varepsilon_0 E _0^2}

Vedclass · Accepted Answer

double the frequency of the wave

Vedclass · Answer

$E=E_0 \sin (\omega t-k x)$

Energy density $\left(\frac{d u}{d v}\right)=\varepsilon_0 E_0^2 \sin ^2(\omega t-k x)$

$\frac{\varepsilon_0 E _0^2}{2}[1-\cos (2 \omega t -2 kx )]$
