Write the SI unit for refractive index.

Is dispersion same as deviation?

Explain the meaning of the term refraction. A ray of monochromatic light is incident from air on a glass slab. Draw a ray diagram indicating the change in its path till it emerges out of the slab.

The diagram shows the path of a ray of light through a rectangular glass block placed in a liquid of uniform density.

What should be the rate of the speed of light through the liquid to the speed through the glass so that there is no refraction of light at the boundaries of the glass block when the system is illuminated by the light of one colour?


The velocity of light in diamond is 121000 kms-1. What is its refractive index?


A coin placed at the bottom of a beaker appears to be raised by 4.0 cm. If the refractive index of water is 4/3, find the depth of the water in the beaker.
