Answer on Acoustics Question for mia
greatest and the smallest wavelengths the ear can detect, assuming the sound travels.
The interrelation between length of a wave and frequency is defined by the following formula: λ = c / f , where "c" - speed of a sound in air, is usually used value of 330 (340) m/s. (The given value depends on temperature and humidity of air, and also from barometric pressure), and "f" - frequency in Hz.
The smallest wavelength λsmall = 330/16000 = 0.50625 m.
The greatest wavelength λgreat = 330/20 = 16.5 m.
The smallest wavelength is 0.020625 m.
The greatest wavelength is 16.5 m.
