The speed of light in a material medium is given by: |
$(\mu \varepsilon)^{-1 / 2}$ $\left(\mu_o \varepsilon_o\right)^{1 / 2}$ $\left(\mu_{o} \varepsilon_{o}\right)^{-1 / 2}$ $(\mu \varepsilon)^{1 / 2}$ |
$(\mu \varepsilon)^{-1 / 2}$ |
The correct answer is Option (1) → $(\mu \varepsilon)^{-1 / 2}$ The speed of light in a given material, $V=\frac{1}{\sqrt{με}}$ where, V - Speed of light in the medium. $μ$ - Permeability of medium $ε$ - Permittivity of medium |
