MCQ
What is the path difference of destructive interference
  • A
    $n \lambda$
  • B
    $n(\lambda+1)$
  • C
    $\frac{(n+1) \lambda}{2}$
  • $\frac{(2 n+1) \lambda}{2}$

Answer

Correct option: D.
$\frac{(2 n+1) \lambda}{2}$
For destructive interference path difference is odd multiple of $\frac{\lambda}{2}$.
