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

Q.

Light travels through a glass plate of thickness $t$ and refractive index $n$. If $c$ is the velocity of light in vacuum, then the time taken by light to travel the thickness of the plate will be:

Q. If the velocity of light in vacuum is $3\times {10}^{8}m{s}^{-1}$, the time taken (in nanosecond) to travel through a glass plate of thickness $10cm$ and refractive index $1.5$ is :

Q. A glass slab of thickness t and refractive index $\mu$. Calculate the time taken by light to travel this thickness.
