    Answer:

    Explanation:

    A pain vibrates 262 times in 5seconds

    The period of a vibration or wave is the time for one complete vibration. When an object makes one vibration per second its frequency is said to be 1 hertz.

    Then, the frequency of oscillation is

    262 / 5Hz

    F = 52.4 Hz

    Then,

    f = 1 / T

    Where

    f = frequency

    T = period

    So, it completes 262 oscillation in 5seconds

    Where one oscillation is one period

    Then,

    Each oscillation will be

    T = 5 / 262

    T = 0.0191 seconds

    T = 19.1 ms

    The period of oscillation is 19.1 ms

    Or by using

    T = 1 / f

    T = 1 / 52.4

    T = 0.0191s

    T = 19.1 ms
