$A$ plane electromagnetic wave is incident on a material surface. If the wave delivers momentum $p$ and energy $E$,then

At an instant,a plane electromagnetic wave has its magnetic field in the direction of the vector $\hat{i}-\hat{j}$ and its electric field is in the direction of $\hat{i}+\hat{j}$. The wave is travelling along which direction?

If a source is transmitting electromagnetic waves of frequency $8.2 \times 10^6 \,Hz$, then the wavelength of the electromagnetic waves transmitted from the source will be (in $\,m$)

The oscillating electric and magnetic vectors of an electromagnetic wave are oriented along

$A$ microwave oven heats food containing water molecules very efficiently under which of the following conditions?

An electric charge oscillating harmonically with frequency $750 kHz$ produces electromagnetic waves of frequency. (Speed of light in vacuum is $3 \times 10^8 \ m/s$) (in $kHz$)
