- Explanation -

 Dispersion refers to the state in which light is scattered or spread out. It refers to the separation of the constituent colors of light, like a rainbow.

 Abbe Number is an optical property that describes how much a transparent material scatters light. It is a measure of chromatic dispersion. A higher Abbe Number indicates less dispersion and less chromatic aberration.
