Sample questions
A plane electromagnetic wave travels through a medium and the magnetic field associated with it is given by
\[B=5\times10^{-8}\sin(3\times10^{10}t-150x)\;\mathrm{T}\]
where x is in metres and t is in seconds.
The velocity of the wave is:
(a) Depict the variation of electric field \((\vec{E})\) and magnetic field \((\vec{B})\) with respect to the direction of propagation of an electromagnetic wave. Write their two important characteristics.
(b) Show that \(\frac{1}{\sqrt{\varepsilon_0\mu_0}}\) gives the velocity of an electromagnetic wave in free space.
