A) \[\lambda =1/6m,\ v=250m/s\]
B) \[a=0.07m,\ v=300m/s\]
C) \[n=1500,\ v=200m/s\]
D) None
Correct Answer: A
Solution :
Comparing the given equation with \[y=a\sin \left( \omega t-kx \right)\] We get \[\omega =3000\,\pi \]Þ \[n=\frac{\omega }{2\pi }=1500\,Hz\] and \[k=\frac{2\pi }{\lambda }=12\pi \Rightarrow \lambda =\frac{1}{6}m\] So, \[v=n\lambda \Rightarrow v=1500\times \frac{1}{6}=250\]\[m/s\]You need to login to perform this action.
