    Two sound waves having a phase difference of\[\text{6}0{}^\circ \], have a path difference of

    A) \[\frac{\lambda }{3}\]                                   

    B) \[\frac{\lambda }{6}\]

    C) \[\frac{\lambda }{9}\]                                   

    D) \[\lambda \]

    Correct Answer: B

    Solution :

    Path difference \[\Delta =\frac{\lambda }{2\pi }\times \Delta \phi \] \[=\frac{\lambda }{2\pi }\times \frac{\pi }{3}=\frac{\pi }{6}\]
