When a beam of white light passes through a prism, the different colors of light are separated due to the difference in their

Explanation

Glass has a slightly different refractive index for each colour. Violet light is slowed and bent the most, and red the least.

So the colours separate because of their different refractive indices. This spreading is called dispersion.
