A) \[\frac{\pi }{8}\]
B) \[\frac{\pi }{4}\]
C) \[\frac{3\pi }{8}\]
D) \[\frac{\pi }{2}\]
Correct Answer: D
Solution :
\[v=n\lambda \Rightarrow \lambda =10\,\,cm\] Phase difference \[\frac{2\pi }{\lambda }\times \]Path difference \[\frac{2\pi }{10}\times 2.5\]= \[\frac{\pi }{2}\]You need to login to perform this action.
