Young's double slit experiment is performed in water, instead of air, then fringe width

Options

  1. Adecreases.
  2. Bbecomes infinite.
  3. Cincreases.
  4. Dremains same.

Correct answer

A. decreases.

Step-by-step solution

(C) X = D d In water the wavelength decreases and hence the fringe width decrease.
