A beam of light composed of red and green rays is incident obliquely at a point on the face of a rectangular glass slab. When coming out on the opposite parallel face, the red and green rays emerge from.

Two points propagating in two different non- parallel directions.

Two points propagating in two different parallel directions

one point propagating in two different directions.

one point propagating in the same direction.

Solution

Two points propagating in two different parallel directions

We know that in any medium except vacuum or air, the velocities of different colours are different. Therefore, both red and green colours are refracted at different, angles of refraction. So, after emerging from glass slab through opposite parallel faces, they appear at two different points an move in two different parallel directions.
