Question

A person has a hearing range from 20 Hz to 20000Hz. What are the typical wavelengths of sound waves in air corresponding to these two frequencies? Take the speed of sound in air as 344 m/s

Answer 1

Explanation:

Take the speed of sound in air as 344 m s-1. Hence, for humans, the wavelength range for hearing is 0.0172 m to 17.2 m.

Answer 2

Answer:

Explanation:

       we know that v = n λ where n is freq and λ is wavelength

                                         v is the speed of light

          substitute the both limits to get the typical wavelengths of sound                      waves in air

    i.e u will get  from 172 x 10 to power -4 to 17.2
