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.

Answer 1

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
