Vedclass · Answer

(A) The velocity of light in a medium is calculated using the formula $v = \frac{c}{\mu}$,where $c$ is the speed of light in a vacuum $(3 	imes 10^{8} \ m \ s^{-1})$ and $\mu$ is the refractive index of the medium.Given,$\mu = 1.5$.Substituting the values: $v = \frac{3 	imes 10^{8}}{1.5} = 2 	imes 10^{8} \ m \ s^{-1}$.Therefore,the velocity of light in the glass slab is $2 	imes 10^{8} \ m \ s^{-1}$.

What is the velocity of light in a glass slab of refractive index $1.5$?
