A) \[350\,m{{s}^{-1}}\]
B) \[330\,m{{s}^{-1}}\]
C) \[300\,m{{s}^{-1}}\]
D) \[450\,m{{s}^{-1}}\]
Correct Answer: B
Solution :
Key Idea: \[Frequecy=\frac{1}{Time-period}\] The relation between velocity \[(v),\] and wavelength \[(\lambda )\] is given by \[v=n\lambda \] where, \[n=\frac{1}{T}\] Given, \[\lambda =\frac{16.5}{25}m,T=\frac{1}{500}s\] Hence, \[v=\frac{\lambda }{T}=\frac{16.5}{25}\times 500=330\,m{{s}^{-1}}\]
