    Sound waves can have lots of different periods (yet travel at the same speed). For example my voice at 500 Hz will have a period of 2 ms. A dog whistle at 50,000 Hz will have a period of 0.02 ms. The period T is one over the frequency f, i.e. T = 1/f.

    Seems to be missing information, is there a frequency given?

    If its part of a multi part question check for any information about wavelength in the earlier parts.
    Use the relationship
    Wave speed = wavelength * frequency
    To get the frequency
