Question

A person has a hearing range from 20Hz to 20 kHz. What are the typical wave length of sound waves in air corresponding to these two frequencies? Take the speed of sound in air as 344m/s

Answer 1

Hi friend
----------------
Your answer
-----------------------

Hearing range = 20Hz to 20kHz

Speed of sound given = 344 m/s

So,
-----

Wavelength = Wave velocity / Frequency

Then,
----------

Wavelength when frequency is 20 Hz = 344/20 m = 17.2 m

Wavelength when frequency is 20000Hz (20kHz) = 344/20000 m =
0.0172 m
