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.

 6 Extrinsic Muscles



- Point Word-

  • 6 Extrinsic Muscles

  • 4 Rectus

  • 2 Oblique



- Explanation -

 

The figure above shows the position and shape of the 6 extrinsic muscles located when the right eye is viewed from the front. There are six muscles in the outer lining. There are four rectus muscles in the upper and lower left and right sides of the eyeball, and two oblique muscles in the upper and lower sides. These muscles are responsible for eye movement.
