In Young's double slit experiment the separation between the slits is doubled without changing other setting of the experiment to obtain same fringe width, the distance ' D ' of the screen from slit should be made

Options

  1. AD 2
  2. BD 2
  3. C2 D
  4. D4 D

Correct answer

C. 2 D

Step-by-step solution

Fringe width, W = D d Given: d =2 ~d W ^ = D ^ 2 ~d Since given, aligned & W = W ^ & D d = D ^ 2 ~d & D ^ =2 D aligned
