A) \[40\,m/s\]
B) \[20\,m/s\]
C) \[10\,m/s\]
D) none of these
Correct Answer: B
Solution :
Here, frequency \[n=100Hz.\] Distance from fixed end \[=10\,cm=0.1m\] When a stationary wave is produced, the fixed end behaves as a node. Thus, wavelength is given by \[\frac{\lambda }{2}=0.1\] \[\lambda =2\times 0.1=0.2m\] Hence, the velocity \[V=n\lambda =100\times 0.2=20\,m/s.\]You need to login to perform this action.
