Question: The two waves represented by y1 = a sin(wt) and $ y _{2}=b\cos (\omega t) $ have a phase difference of
[MP PMT 2000]
Options:
A) 0
B) $ \frac{\pi }{2} $
C) p
D) $ \frac{\pi }{4} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ y _{1}=a\sin \omega t, $ and $ y _{2}=b\cos \omega t=b\sin ( \omega t+\frac{\pi }{2} ) $ So phase difference $ \varphi =\pi /2 $
