MCQ
In a wave, the path difference corresponding to a phase difference of $ \phi$  is
  • A
    $\frac{\pi }{{2\lambda }}\phi$
  • B
    $\frac{\pi }{\lambda }\phi $
  • $\frac{\lambda }{{2\pi }}\phi$
  • D
    $\frac{\lambda }{\pi }\phi$

Answer

Correct option: C.
$\frac{\lambda }{{2\pi }}\phi$
c
(c)For $2$ $\pi$  phase difference $\to$ Path difference is $\lambda$
 For $\phi $ phase difference $\to$ Path difference is $\frac{\lambda }{{2\pi }} \times \phi$
