1.

For a person with normal hearing, the limit of audibility is 20 Hz to 20000 Hz. If so, what will be the limit of wavelength of sound waves that are audible to human beings? Assume that the speed of sound is 340 m/s.

Answer»

f = 20 Hz,

v = f λ ,

λ = v/f = 17m

f = 20000Hz,

v = f λ,

λ = 0.017 m

so limit of wavelength = 0.017 to 17

= 0.017 to 17 m
