Solution:-
The audiable waves of a man is 20Hz to 20,000Hz.
The speed of sound in the air is 340m/s.
As we know that,
Speed of sound= Wavelenth × Frequency
When frequency is 20Hz
then wavelength=340/20=17 m
When frequency is 20KHz
then wavelength
= 340/20000 (20KHz = 20000Hz)
=0.0170m
[Answer:- 0.0170 m]
