Practicing Success
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) → $(\mu \varepsilon)^{-1 / 2}$ |
