Refractive index of medium is \mathrm{=\frac{c}{v}}

Where \mathrm{c=\frac{1}{\sqrt{\mu 0 \varepsilon_0}} \text { and } v=\frac{1}{\sqrt{\mu_0 \varepsilon_0 \mu_r \varepsilon_r}}}

\mathrm{\therefore \quad \mu=\frac{1 / \sqrt{0_{00}}}{1 / \sqrt{\mu_0 \varepsilon_0 \mu_r \varepsilon}}=\sqrt{\mu_r \varepsilon_r}}

Given \mathrm{\mu_r=\mu_0} and \mathrm{\varepsilon _r=\varepsilon _0} then \mu=\sqrt{\mu_{0 \varepsilon 0}}
