Vedclass · Answer

(C) The thickness of the glass plate is given as $t$.The refractive index of the glass is $\mu$.The velocity of light in vacuum is $c$.The velocity of light in a medium $(v)$ is related to the refractive index $(\mu)$ and the velocity of light in vacuum $(c)$ by the formula: $\mu = \frac{c}{v}$.Therefore,the speed of light in the glass plate is $v = \frac{c}{\mu}$.The time $(T)$ taken to travel a distance $(t)$ at a constant speed $(v)$ is given by $T = \frac{	ext{distance}}{	ext{speed}} = \frac{t}{v}$.Substituting the value of $v$: $T = \frac{t}{c / \mu} = \frac{\mu t}{c}$.Thus,the time taken is $\frac{\mu t}{c}$.

Light travels through a glass plate of thickness $t$ and having refractive index $\mu$. If $c$ is the velocity of light in vacuum,the time taken by the light to travel through this thickness of glass is:
