The range of human hearing extends from approximately 20 Hz to 20 000 Hz. Find the wavelengths of these extremes when the speed of sound in air is equal to 337 m/s.

Respuesta :

Answer:

0.01685 m to 16.85 m

Explanation:

given,

range of human ear= 20 Hz to 20000 Hz

speed of the sound,v = 337 m/s

wavelength of the sound = ?

we know,

[tex]\lambda = \dfrac{v}{f}[/tex]

now, for f = 20 Hz

[tex]\lambda = \dfrac{337}{20}[/tex]

[tex]\lambda =16.85\ m[/tex]

for f = 20000 Hz

[tex]\lambda = \dfrac{337}{20000}[/tex]

[tex]\lambda =0.01685\ m[/tex]

range of the wavelength comes out to be

  = 0.01685 m to 16.85 m
