The range of human hearing extends from approximately 20 Hz to 20000 Hz. Find the wavelength of these extremes when the speed of sound in air is equal to 343 m/s.

  • Physics -

    distance = rate * time
    since period is 1/frequency then
    wavelength = speed of sound *(1/frequency)
    so
    343 *(1/20) = 343/20 = 17.15 m
    and
    343 * (1/20,000) = 343/20,000 = .01715 m = 1.7 cm or about 11/16 of an inch
