STATEMENT-1 : Fringe width depends upon refractive index of the medium. STATEMENT-2 :Refractive index changes optical path of ray of light forming fringe pattern.

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

B. Statement - 1 is True, Statement - 2 is True; Statement - 2 is NOT a correct explanation for Statement - 1.
