    In a sinusoidal wave, the time required for a particular point to move from maximum displacement to zero displacement is 0.17s. The frequency of the wave is

    A)  1.47 Hz        

    B)  0.36 Hz

    C)  0.73 Hz        

    D)  2.94 Hz

    Correct Answer: A

    Solution :

     Time for maximum displacement \[t=0.17\text{ }s\] Time period T for one vibration \[=4t=4\times 0.17=0.68s\] Frequency \[=\frac{1}{time\text{ }period\,(T)}=\frac{1}{0.68}\] \[=1.47\text{ }Hz\]
