Assertion : In YDSE bright and dark fringe are equally spaced. Reason : It only depends upon phase difference.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

C. If assertion is true but reason is false.

Step-by-step solution

Fringe width is given by, = D d where, D= distance between stil and screen, d= distance between coherent sources of light and = wavelength of incident light.
