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 \[\Delta \,\phi =\frac{2\pi }{\lambda }\Delta \,x\] \[\frac{\pi }{3}=\frac{2\pi }{\lambda }\Delta x\] \[\Delta \,x=\frac{\lambda }{6}\]You need to login to perform this action.
