Question

A glass slab made of a material of refractive index n1 is kept in a medium of refractive index n2. A light ray is incident on the slab. Complete the path of rays of light energing from the glass slab, if: a)n1n2 b) n1=n2 c) n1

Answer 1

• If n1> n2, the ray will pass from one medium to another however it will bend towards the normal while entering the medium with refractive index n2.

• It occurs because the density of the medium 2 is greater than the medium 1.

• If n1=n2, there will be no diversion in the path of the ray

• If n1>n2, the ray will bend away from the normal.

Answer 2

Answer:

If n2> n1, the ray will pass from one medium to another it will bend towards the normal while entering the medium with refractive index n2.

It happens because the density of the medium 2 is greater than meaium 1

If n1=n2, there will be no diversion in the path of the ray

If n1>n2, the ray will bend away from the normal

It happens because the density of the medium 1 is greater than meaium 2
