Define dispersion of light.

Solution 1
The phenomenon of the splitting of white light by a prism into its constituent colours is known as dispersion of light.
Solution 2
When a beam of white light or composite light is refracted through any transparent media such as glass or water, it is split into its component colours. This phenomenon is called ‘dispersion of light’.
