A narrow beam of white light enters slab having parallel faces.

A

The light never splits in different colours

B

The emergent beam is white

C

The light inside the slab is split into different colours

D

The light inside the slab is white

Text Solution

Verified by Experts

The correct Answer is:
b,c
The light splits in different colours inside the slab due to dispersion.
But the emergent rays will be paeallel and will overlap with others hence giving white emergent beam. Inside the slab rays of different colours are not parallel and they intersect each other.
