If \(\varepsilon_{0}\) and \(\mu_{0}\) are the electric permittivity and magnetic permeability in free space, \(\varepsilon\) and \(\mu\) are corresponding quantities in a medium, then index of refraction of the medium is
- \(\sqrt{\frac{\varepsilon_{0} \mu}{\varepsilon \mu_{0}}}\)
- \(\sqrt{\frac{\varepsilon}{\varepsilon_{0}}}\)
- \(\sqrt{\frac{\varepsilon_{0} \mu_{0}}{\varepsilon \mu}}\)
- \(\sqrt{\frac{\varepsilon \mu}{\varepsilon_{0} \mu_{0}}}\)
Answer
(D) _ 0 _ 0
