When light propagates through a material medium of relative permittivity $\displaystyle \epsilon_{\mathrm{r}}$ and relative permeability $\displaystyle \mu_{\mathrm{r}}$, the velocity of light, $\displaystyle v$ is given by : (c - velocity of light in vacuum)
Official answer
From NTA’s final answer key for this paper.
(1)
$\displaystyle v=\frac{c}{\sqrt{\epsilon_{\mathrm{r}} \mu_{\mathrm{r}}}}$
