The average range of frequencies at which human beings can hear sound waves varies from 20 Hz to 20 kHz. Calculate the wavelength of the sound wave in these limits . (Assume the speed of sound to be `340 ms^(-1)`

Explanation

`lambda_1 = v/f_1 = (340)/(20) = 17 m`
`lambda_2 = v/f_2 = (340)/(20xx 10^3) =- 0.017 m`
therefore , the audible wavelenght region is from 0.017 m to 17 m when the velocity of sound in that region is 340 `ms^(-1)`
