    Answer:

    the frequency of a wave is equal to the linear speed divided the wavelength. so in equation form.

    f = v / l

    where f is the frequency

    v iss the linear speed

    l is the wavelength

    f = ( 345 m/s ) / ( 4.38 mm ) ( 1 m / 1000 mm )

    f = 78767 per second

    Explanation:

    hope it helps
