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

    A)  1.47 Hz         

    B)  2.94 Hz

    C)  0.73 Hz         

    D)  0.36 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 \[=\frac{1}{time\text{ }period(T)}\] \[=\frac{1}{0.68}\] \[=1.47\text{ }Hz\]
