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.

Chiasm (Optic Chiasm)


- Point -

 Chiasm - The point where the optic nerves from each eye are combined



- Point Word-

  • Chiasm
  • The point where the optic nerves from each eye are combined



- Explanation -

  

The Optic Chiasm is the part of the brain where the optic nerves of each eye cross. Damage to the Optic Chiasm, where the optic nerves cross, will result in visual field loss in the eye corresponding to the damaged area.
