    Answer: f = 6.5Hz

    Explanation:

    Given that the

    Speed V = 65 m/s

    Wavelength (λ) = 10m

    Wave speed is the product of frequency and wavelength. That is,

    V = fλ

    Substitute V and (λ) into the formula to get frequency f

    65 = 10f

    Make f the subject of formula

    f = 65/10

    f = 6.5 Hz

    Therefore, the frequency of this wave is 6.5 Hz?
