Consider the following statements about interference of light. A-When crest of one wave coincides with crest of another wave at point, this point is a point of destructive interference. B-Two coherent sources emit wave of same frequency with constant phase difference. Choose the correct option from the following.

Options

  1. ABoth statements A and B are wrong.
  2. BStatement A is correct while statement B is wrong.
  3. CStatement B is correct while statement A is wrong.
  4. DBoth statements A and B are correct.

Correct answer

C. Statement B is correct while statement A is wrong.

Step-by-step solution

The correct option is (C). Statement A is false as the point where two crests coincide is the point of constructive interference. Statement B is true, because coherent sources emit waves of same frequency.
