A) 150 m/s
B) 300 m/s
C) 350 m/s
D) 250 m/s
Correct Answer: B
Solution :
Given equation is \[y=0.5\text{ }sin\text{ }\pi \text{ (}0.01\text{ }x-3t\text{)}\] or \[y=0.5\sin \,(0.01\pi x-3\pi t)\] ... (i) Standard equation of wave is \[y=A\sin \,(kx-\omega t)\] ?(ii) Comparing equations (i) and (ii), we get \[k=0.01\,\pi \] and \[\omega =3\pi \] We know that \[k=\frac{\omega }{\upsilon }\]or \[\upsilon =\frac{\omega }{k}=\frac{3\pi }{0.01\pi }=300\,m/s\]
