Question

Most people can detect frequencies as high as 20 000 Hz. Assuming the speed of sound in air is 345 m/s, determine the wavelength of the sound corresponding to this upper range of audible hearing.

Answer 1

Wavelength = speed / frequency

(345 m/s) / (20,000 Hz) = 0.017 m

Answer 2

Formula to solve for the wavelength: w = s/f

w = wavelength

s = speed

f = frequency

Solve using the given values.

w = 345/20000

w = 0.01725

Round if necessary.

0.0173

Therefore, the wavelength is approximately 0.0173 meters.

Best of Luck!
