Question

a person can hear sound waves in the frequency range 20 htz to 20 kilo htz find the minimum and the maximum wavelength of sound that is audible to the person the speed of a sound is 340 M per second

Answer 1

v=υλ   given v=340m/s  υ=20Hz  λ=v/υ
λ=340/20
λ=17m
case 2   v=340m/s   υ=20,000Hz
v=υλ  or λ=v/λ
λ=340/20,000
λ=0.017m
