A) \[\pi \]
B) \[2\pi \]
C) \[\frac{\pi }{2}\]
D) \[4\pi \]
Correct Answer: D
Solution :
\[\operatorname{Phase} difference =\,\,\frac{2\pi }{\lambda }\times path difference\] \[\operatorname{Path} difference =9-5=4\] \[Wavelength\,\,\lambda =2\] \[\operatorname{Phase} difference =\,\,\frac{2\pi }{2}\times 4=4\pi \]You need to login to perform this action.
