A) 1 cm
B) 6 cm
C) 12cm
D) 24cm
Correct Answer: C
Solution :
The wavelength\[\lambda =\frac{v}{f}=\frac{360\times 100}{500}=72\,cm\] Path difference \[=\frac{\lambda }{2\pi }\times \]phase difference \[=\frac{\lambda }{2\pi }\times \frac{\pi }{3}=\frac{\lambda }{6}=12\,cm\]You need to login to perform this action.
