The average range of frequencies at which human beings can hear sound

1.	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)
Answer» SOLUTION :`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)`
