    The formula for calculating wavelength ʎ is:

    ʎ = s / f

    where ʎ is wavelength, s is speed of sound, f is frequency

    ʎ (large organ pipe) = (344 m/s) / (30 s-1) = 11.47 m

    ʎ (piccolo) = (344 m/s) / (1.5x10^4 s-1) = 0.023 m

    So the difference is:

    11.47 - 0.023 = 11.45 m

    Answer:

    11.45 m
