Dispersion = Abbe Number or Constringency Value and Nu Value

- Point -  Dispersion is categorized by Abbe Number or as it is also known by Constringency Value or Nu Value. - Point Word- Dispersion Abbe Number Constringency Value Nu Value - 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.
