A glass slab made of a material of refractive index n1

• Reflection & Refraction (C10)

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. Draw the path of the rays of light emerging from the glass slab, if (i) n₁ > n₂ (ii) n₁ = n₂ (iii) n₁ < n₂

Answer

1. The ray moves towards the normal.

2. The ray moves undeviated.

3. The ray moves away from the normal.
