    Answer:

    f = 2200 Hz

    Explanation:

    It is given that,

    Speed of a wave is 242 m/s

    The distance between crests is 0.11 m

    We need to find the frequency of the wave. The distance between crests is called wavelength of a wave. So,

    v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{242}{0.11}\\\\f=2200\ Hz

    So, the frequency of the wave is 2200 Hz.
