    If the phase difference between two sound waves of wavelength is \[60{}^\circ \], the corresponding path difference is:

    A) \[\frac{\lambda }{2}\]                            

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

    C) \[2\lambda \]                             

    D) \[\frac{\lambda }{4}\]

    Correct Answer: B

    Solution :

    [b] Phase difference \[=\frac{2\pi }{\lambda }\times \] path difference \[\Delta \,\phi =\frac{2\pi }{\lambda }\Delta \,x\] \[\frac{\pi }{3}=\frac{2\pi }{\lambda }\Delta x\] \[\Delta \,x=\frac{\lambda }{6}\]
