If two light waves reaching at a point produce destructive interference, then condition of phase difference is

• A

  $0,2 \pi, 4 \pi, 6 \pi \ldots \ldots$
• B

  $\frac{\pi}{4}, \frac{\pi}{2}, \frac{3 \pi}{4} \ldots \ldots$
• C

  $\frac{\pi}{2}, \frac{3 \pi}{2}, \frac{5 \pi}{2} \ldots \ldots$
• Correct answer
  D

  $\pi, 3 \pi, 5 \pi \ldots \ldots$

Hence, the correct answer is option: 'D'.
