The electric and the magnetic field in an electromagnetic wave are:

An electromagnetic wave going through a vacuum is described by, $E=E_0\sin \left(kx-\omega t\right)$. Which of the following is/are independent of the wavelength?

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

A point source of electromagnetic radiation has an average power output of $800 \mathrm{W}$. The maximum value of the electric field at a distance $4.0 \mathrm{m}$ from the source is

A plane electromagnetic wave travelling along the $X$-direction has a wavelength of $3 \mathrm{mm}$. The variation in the electric field occurs in the $Y$-direction with an amplitude $66 \mathrm{V} {\mathrm{m}}^{–1}$. The equation for the electric and magnetic fields as a function of $x$ and $t$ are, respectively.
