The ratio of the magnitude of the magnetic field and electric field intensity of a plane electromagnetic wave in free space of permeability $\mu_0$ and permittivity $\varepsilon_0$ is (Given that $c$ - velocity of light in free space):
$c$
$\frac{1}{c}$
$\frac{c}{\sqrt{\mu_0 \varepsilon_0}}$
$\frac{\sqrt{\mu_0 \varepsilon_0}}{c}$
Solution
As per question,
$\frac{\mathrm{B}_0}{\mathrm{E}_0}=\frac{1}{c}=\sqrt{\mu_0 \varepsilon_0}$
(where, the symbols have their usual meanings.)
