[MP PET 2000]

Options:

A) $ \frac{\pi }{2\lambda }\varphi $

B) $ \frac{\pi }{\lambda }\varphi $

C) $ \frac{\lambda }{2\pi }\varphi $

D) $ \frac{\lambda }{\pi }\varphi $

Show Answer

Answer:

Correct Answer: C

Solution:

For 2p phase difference Path difference is l

For f phase difference

Path difference is $ \frac{\lambda }{2\pi }\times \varphi $
