A plane electromagnetic wave of frequency $30 \mathrm{MHz}$ is travelling along $\hat{\mathrm{k}}$ - direction. At a particular point of space and time of propagation, if the electric field is given by $\overrightarrow{E}=30 \mathrm{Volts} {\mathrm{meter}}^{-1}$ $\left(-\hat{\mathrm{i}}\right),$ then the corresponding magnetic field is

If the intensity of sun light outside earth's atmosphere is $1.4 \mathrm{kW} {\mathrm{cm}}^{-2}$, the corresponding maximum electric field amplitude is, approximately (Assume ${\mu }_0=4\pi \times {10}^{-7} \mathrm{H} {\mathrm{m}}^{-1}$)

The permeability of a medium whose refractive index is $1.5$ and permittivity is $4.43\times {10}^{-11} \mathrm{F} {\mathrm{m}}^{-1}$ is

A plane electromagnetic wave of frequency $10MHz$ travels in free space in $X-Y$ plane making an angle of $45°$ with $+x.$ - axis. At a patticular point in space and time, $\overrightarrow{E}=6\hat{k}V/m.$ What is $\overrightarrow{B}$ at this point?

Maxwell's equation is applicable for electromagnetic waves of

A charged particle oscillates about its mean equilibrium position with a frequency ${10}^{11} \mathrm{Hz}.$ The frequency of the EM- waves produced by the oscillator is
