Question

Why does the white light not split into different colours when it passes through a glass slab?

Answer 1

Hey mate..

Here's your answer...

____________________________________________

We have already seen that when we join two prisms
in inverted form light seems to recombine...i.e the white light
splits into 7colours and then again recombine into 1(white).

Thus..a glass slab is meant to be as recombination of prism.
So splitting does not occur.
