Newton's ring pattern in reflected system, viewed under white light consists of

Options

  1. Aequally spaced bright and dark bands with central dark spot
  2. Bequally spaced bright and dark bands with central white spot
  3. Ca few coloured rings with central dark spot
  4. Da few coloured rings with central white spot

Correct answer

A. equally spaced bright and dark bands with central dark spot

Step-by-step solution

Newton's rings are fringes of equal thickness. These circular fringes were discovered by Newton, hence called Newton's rings. These rings are formed with equally spaced bright and dark band with central spot as dark.
