Doppler Effect in Light

An electromagnetic wave is travelling in a medium with a velocity $\overrightarrow{v}=v\widehat{i}$ . The electric field oscillations, of this electromagnetic wave wave, are along the y – axis.

(a) Identify the direction in which the magnetic field oscillations are taking place, of the electromagnetic wave wave.

(b) How are the magnitudes of the electric and magnetic fields in the electromagnetic wave related to each other?

The electric field of a plane electromagnetic wave propagating along the z-axis varies with time with an amplitude of $2\mathrm{ }\mathrm{V} {\mathrm{m}}^{-1}$. The average energy density of the magnetic field (in $\mathrm{J}\mathrm{ }{\mathrm{m}}^{-3}$) is :

Do electromagnetic waves carry momentum and energy

Electric field amplitude of electromagnetic wave is $240 {\mathrm{NC}}^{-1}$ and frequency $50 \mathrm{MHz}$, if the wave is propagating along $\mathrm{x}-\mathrm{axis}$ then equation of wave for electric field is

Magnitude of wave vector is reciprocal to wavelength and direction perpendicular to wavelength.

Electromagnetic waves propagating along $\mathrm{x}-\mathrm{axis}$, the equation for electric field along $\mathrm{y}-\mathrm{axis}$ is expressed as ${\mathrm{E}}_{\mathrm{y}}={\mathrm{E}}_0 \sin 2\mathrm{\pi }\left(\frac{\mathrm{x}}{\mathrm{\lambda }}-\frac{\mathrm{t}}{\mathrm{T}}\right)$, the wave vector is
