Verified Answer
?A person has a hearing range from 20hz to 20khz .whatare typical wave...
Given frequencies are 20 Hz and 20 kHz and Velocity = 344ms^-1
We know that velocity = wavelength * frequency. It can also be written as
wavelength = Velocity/Frequency.
(i) Consider frequency = 20Hz
Wavelength = 344/20
= 17.2m.
(ii) Consider frequency = 20kHz.
Wavelength = 344/20000
= 0.0172 m.
