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? the speed of sound in air is 344 m/s.

The wavelength is related to the frequency by the relationship:

where v is the wave speed and f is its frequency.

The speed of sound in air is v=344 m/s. The lowest frequency is f=20.0 Hz, so the corresponding wavelength is

The highest frequency is , so the corresponding wavelength is


Therefore, the range of wavelengths of audible sound in air is
[0.017 m - 17.2 m]

Then the answer would be d then
