A) 150 m/s
B) 300 m/s
C) 350 m/s
D) 250 m/s
Correct Answer: B
Solution :
Standard equation of wave of amplitude A and angular velocity o is given by \[y=A\,\sin \,(kx-\omega t)\] ... (i) Given equation is \[y=0.5\,\,\sin \,\,\pi \,(0.01\,x-3\,t)\] ... (ii) Comparing Eqs. (i) and (ii), we get \[k=0.01\,\pi \], \[\omega =3\pi \] Also, \[v=\frac{\omega }{k}\] \[=\frac{3\,\pi }{0.01\,\pi }=300\,m/s\]You need to login to perform this action.
