List of top Physics Questions on Electromagnetic Wave

An electromagnetic wave travelling in a lossless dielectric medium having a dielectric constant, \[ \varepsilon_r = 9, \] has the electric field \[ E_x=E_0\sin(kz-2\pi\times10^6 t)\ \text{V m}^{-1} \] where \(E_0\) is the amplitude and \(k\) is the wave vector. Among the following options, the incorrect choice is:

The electric field E associated with a progressive electromagnetic wave is given by E = E\(_0\)sin(kx - \(\omega\)t). If B\(_0\) is the amplitude of the magnetic field associated with the wave, then
