Question

the refractive indicies of some media are listed below name the media in which the velocity of light is minimum and maximum. medium and refractive index k 1.62 , L 1.81 , M 1.94, N 2.43​

Answer 1

Velocity of light will be maximum in k1.72 and minimum in N2.43

Answer 2

The refractive index is minimum in case of medium with refractive index 2.43 ( N) .

And the refractive index is maximum in case of medium with refractive index 1.62 ( K).

It is because velocity of light in a medium is inversely proportional to the refractive index of the medium, i.e. as the refractive index increases, light travels with a lower velocity and vice-versa.
