    What will be the wave velocity, if the radar gives 54 waves per min and wavelength of the given wave is 10 m                                                                                                [RPET 2000]

    A)            4 m/sec                                  

    B)            6 m/sec

    C)            9 m/sec                                  

    D)            5 m/sec

    Correct Answer: C

    Solution :

               \[n=\frac{54}{60}Hz,\,\lambda =10\,m\]Þ\[v=n\lambda =9\,m/s\].
