Question

how will u define the dispersion of light? how Newton's disc demonstrate the reversed process of diperson of light​

Answer 1

Explanation:

Dispersion of light is defined as the spreading of white light into seven colors due to the change in the velocity of the colors.

Newton's prism experiment, we can see that he places a prism in an inverted position next to a prism with it's base on the ground. While the first prism scatters white light into seven colors, the inverted prism recombines the seven colors into a white light.
