A) \[\pi /\text{3}\]
B) \[\pi /\text{6}\]
C) \[\pi /\text{2}\]
D) \[\pi \]
Correct Answer: A
Solution :
Equations of waves is \[x=a\,\,\sin (\omega t+\pi /6)\] \[{{x}^{1}}=a\,\,\cos \,\omega t\] \[=a\,\sin (\omega t-\pi /2)\] Comparing these equations with \[x=a\,\sin (\omega t+\phi )\] \[{{\phi }_{R}}=\frac{\pi }{6},\,{{\phi }_{2}}=\frac{\pi }{2}\] Phase difference \[\Delta \phi =\frac{\pi }{2}-\frac{\pi }{6}=\frac{\pi }{3}\]
