Newton's ring pattern in reflected system, viewed under white light consists of
- A equally spaced bright and dark bands with central dark spot
- B equally spaced bright and dark bands with central white spot
- C a few coloured rings with central dark spot
- D a few coloured rings with central white spot
Answer & Solution
Correct Answer
(A) equally spaced bright and dark bands with central dark spot
Step-by-step Solution
Detailed explanation
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.
