Asked by Lena
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.

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
