    A)  4.0 s                                     

    B)  8.0 s

    C)  2.0 s                                     

    D)  0.25 s

    Correct Answer: A

    Solution :

                     The required relation can be given as                                 \[v=n\lambda \] Given, \[v=25\,m/s,\,\lambda =100\,m\] \[\therefore \]  \[25=n\times 100\] \[\Rightarrow \]               \[n=\frac{25}{100}=\frac{1}{4}\] \[\Rightarrow \]               n = 0.25 Then,    \[T=\frac{1}{n}=\frac{1}{0.25}=4\,s\]
