STATEMENT - 1 : In Young's double slit experiment interference pattern disappears when one of the slits is closed. STATEMENT-2 : Interference occurs due to superimposition of light wave from two coherent sources.

Options

  1. AStatement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.
  2. BStatement -1 is True, Statement - 2 is True; Statement - 2 is NOT a correct explanation for Statement - 1.
  3. CStatement - 1 is True, Statement - 2 is False.
  4. DStatement - 1 is False, Statement - 2 is True.

Correct answer

A. Statement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.

Step-by-step solution

When one of the slits is closed, there appears general illumination from a single source. Interference does not take place.
