The refractive index of water is `4/3` . Find the speed of light in water.

Light enters from air to diamond which has refractive index of 2.42. Calculate the speed of light in diamond . The speed of light in air is 3.0 xx 10^8 m s^-1

Define the refractive index of a medium.

The refractive index of water w.r.t. air is 1.3 and that of glass is 1.5. Calculate the refractive index of water w.r.t. glass.

Light enters from air to glass having refractive index 1.50. What is the speed of light in the glass? The speed of light in vacuum is 3 × 108 m/s .

The refractive index of diamond is 2.42. What is the meaning of this statement?

The value of refractive index of a medium does not depend on the colour of light.
