Physics - EM Waves Question with Solution | TestHub

The energy contained in a small volume through which an electromagnetic wave is passing oscillates with the frequency of the wave.

Magnetic energy has zero average value in a plane electromagnetic wave.

Intensity in electromagnetic wave is given by $\frac{1}{2}{\epsilon }_0{\mathrm{E}}_0^2\mathrm{c}$ where ${\mathrm{E}}_0$ is maximum electric field.

Energy density of electromagnetic wave is given by $\frac{1}{4}{\epsilon }_0{\mathrm{E}}_0^2$.
