What range of sound wavelengths in air at room temperature are audible to a human with ideal hearing (f= 20 hz - 20 khz)?

0.017 m - 17 m

Explanation:

The relationship between wavelength and frequency of a wave is:

where v is the speed of the wave, the wavelength and f the frequency.

The speed of sound waves in air at room temperature is

v = 340 m/s

For the lowest frequency, f = 20 Hz, the wavelength is

For the highest frequency, f = 20 kHz = 20,000 Hz, the wavelength is

close lines strong magnet less close weaker

reserve is the answer
