Q. In a wave, the path difference corresponding to a phase difference of $\phi$ is
A) $\frac{\pi}{2\lambda}\phi$
B) $\frac{\pi}{\lambda}\phi$
C) $\frac{\lambda}{2\pi}\phi$
D) $\frac{\lambda}{\pi}\phi$
Explanation
(c) For $2\pi$ phase difference $\rightarrow$ Path difference is $\lambda$
$\therefore$ For $\phi$ phase difference $\rightarrow$ Path difference is $\frac{\lambda}{2\pi} \times \phi$
