    The wavelengths of C1 is 10.4m, A6 is 0.193m and B7 is 0.0861m

    Explanation:

    Using the formula V = f*λ. Then substitute the following values into the formula:

    a) v=340m/s

    f=32.7 Hz

    λ=V : f

    = 340 : 32.7

    = 10.4m (3s. f)

    b) λ=340 : 1760

    = 0.193m (3s. f)

    c) λ=340:3951.1

    = 0.0861m (3s. f)
