List of top Physics Questions on Electromagnetic waves asked in AP EAMCET

A beam of light with intensity \(10^{-3} \, Nm^{-2}\) and cross sectional area \(20 \, cm^2\) is incident on a fully reflective surface at angle \(45^\circ\). Then the force exerted by the beam on the surface is

A plane electromagnetic wave travels in free space along \(z\)-axis. At a particular point in space, the electric field along \(x\)-axis is \(8.7 \, Vm^{-1}\). The magnetic field along \(y\)-axis is

If the average power per unit area delivered by an electromagnetic wave is
\[ 9240\ \text{W m}^{-2} \] then the amplitude of the oscillating magnetic field in the EM wave is
