Question

If velocity of light in a medium is 2 x 10^8m/s , what is the refractive index of the medium

Answer 1

The refractive index of the medium is 1.5

Given data :

Velocity of the light in that medium = 2×10^8 m/s

We know that, the velocity of light in vacuum = 3×10^8 m/s

Now,

Refractive index = ( Velocity of light in vacuum / Velocity of light in that medium) = (3×10^8 / 2×10^8) = 1.5 (answer)

Answer 2
