A person has a hearing range from 20 Hz to 20 kHz. What are the typical wavelengths of sound waves in air corresponding to these two frequencies? Take the speed of sound in air as.
For 20Hz sound waves the wavelength would be v n v n/ 344 / 20 17.2m For 20kHz sound waves the wavelength would be v n 1 v n/ 344 ms / 20000 Hz 0.0172 m
since air has 344m/s speed of sound hence, the hearing range is 0.0172 to 17.2m
