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

    B)  \[\frac{\lambda }{6}\]

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

    D)  \[\lambda \]

    Correct Answer: B

    Solution :

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