A) 1.2m
B) 12m
C) 2.1 m
D) 0.21m
Correct Answer: B
Solution :
Phase difference\[\frac{2\pi }{\lambda }\] path difference \[\phi =\frac{2\pi }{\lambda }\Delta x\] \[\phi =\frac{2\pi n}{\upsilon }\Delta x\] \[\Rightarrow \] \[\frac{\pi }{3}=\frac{2\pi \times 5}{360}\times \Delta x\] \[\Delta x=12m\]You need to login to perform this action.
