Question

A man has an audible range from 20 Hz to 20 KHz. What are the wavelengths of sound in
corresponding to these two frequencies? (Speed sound in air is 344 m/s)

Answer 1

hi dude

speed of sound= wavelenth * frequency

when frequency is 20Hz

then wavelength=344/20=17.2m

when frequency is 20KHz

then wavelength= 344/20000    (20KHz = 20000Hz)

=0.0172m

hope my ans helps u
