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

    A)  0.38 Hz       

    B)  0.78 Hz

    C)  2.9 Hz        

    D)  1.56 Hz

    Correct Answer: D

    Solution :

     Here: Time required for maximum displacement\[t=0.17\text{ }sec\] We know that the period of sinusoidal wave \[T=4t=4\times 0.16=0.64\] Now frequency of wave \[v=\frac{1}{T}=\frac{1}{0.64}=1.56\,Hz\]
