Answer 2

Explanation:

The first prism P1 disperses the white light into seven colours. The second prism P2receives these seven colours and recombines them into white light. Thus a beam of white light emerges from the other side of the second prism. This observation gave Newton the idea that the sunlight is made of seven colours.
