Question:

For a medium with permittivity ε and permeability µ, the velocity of light is given by:

Options:

$\sqrt{\mu / \varepsilon}$

$\sqrt{\mu \varepsilon}$

$\sqrt{\mu \varepsilon}$

$\sqrt{\varepsilon / \mu}$

Correct Answer:

$\sqrt{\mu \varepsilon}$

Explanation:

For a medium with permittivity ε and permeability µ, velocity of light is given by c = $\frac{1}{\sqrt{\mu \varepsilon}}$
