    Answer: 12.5m

    Explanation:

    Given the following:

    Flagpole makes 20 complete vibrations in 10 seconds

    Velocity (V) of vibration = 25m/s

    Find the wavelength of vibration (λ) = ?

    Frequency is number of complete oscillation per Second

    Therefore;

    Frequency (F) = number of oscillations / time taken

    F = 20 / 10 = 2Hz

    Wavelength = Velocity / frequency

    Wavelength = 25 / 2

    Wavelength = 12.5m
