Audible wavelengths. the range of audible frequencies is from about 20.0 hz to 2.00*104 hz. what is range of the wavelengths of audible sound in air?

Given:

f1 = 20 Hz

f2 = 20000 Hz

speed of sound at 20 degrees celcius = 343 m/s

Solution:

for f1 = 20 Hz,

Using the equation:

lambda = speed of sound / f1 = 343 / 20 = 17.15 m

For f2:

lambda = speed of sound / f2 = 343 / 20000 = 0.01775 m

Therefore the wavelength range of audible sound in air would be 17.15 m to 0.01775 m.
