In an electromagnetic wave,the electric field intensity is $100 \ Vm^{-1}$ and the magnetic intensity is $H_0 = 0.265 \ Am^{-1}$. The maximum intensity of radiation is ..... $Wm^{-2}$.

The velocity of electromagnetic radiation in a medium of permittivity $\varepsilon_{0}$ and permeability $\mu_{0}$ is given by

Which of the following is not a property of light?

In the region far from the source,how are the oscillating electric and magnetic field vectors of an electromagnetic wave oriented?

All electromagnetic waves transport energy in the negative $z$ direction. At a certain point and time,the direction of the electric field of the wave is along the positive $y$ direction. What will be the direction of the magnetic field of the wave at that point and instant?

The magnitude of the electric field of a plane electromagnetic wave travelling in free space is $E$. If $\mu_0$ and $\varepsilon_0$ are respectively permeability and permittivity of the free space,then the magnitude of magnetic field of the wave is
