Calculate the velocity of light in a glass block of refactive index $1.5$. Velocity of light in air = $3.0\times {10}^{8}m{s}^{-1}$

Q.

The velocity of light in a glass block of refractive index 1.5 is:

(Velocity of light in air = 3 x 10⁸ m s^-1 )

Q. The velocity of light in glass whose refractive index w.r.t air is $1.5$ is $2\times {10}^{8}m/s$. In a certain liquid, the velocity of light is found to be $2.5\times {10}^{8}m/s$. The refractive index of the liquid w.r.t air is

Q. Velocity of light in glass whose refractive index with respect to air is 1.5 is $2\times {10}^{8}m{s}^{-1}$ and in certain liquid the velocity of light found to be $2.50\times {10}^{8}m{s}^{-1}$.The refractive index of the liquid
with respect to air is

Q. The velocity of light in a medium is $1.5\times {10}^{8}m/s$. What is the refractive index of the medium with respect to air, if the velocity in air is $3\times {10}^{8}m/s$?

Q.

A ray of light travelling from medium I in which speed of light is $2\times {10}^{8}m/s$ to a medium II in which speed of light is $1.5\times {10}^{8}m/s$. Choose the correct ray diagram:

I. $u=2\times {10}^{8}m/s$

II. $v=1.5\times {10}^{8}m/s$
