At what sound frequency will the wavelength equal the distance between a pair of human ears (10 cm)? (Note: The ability to locate the direction of a sound wave becomes worse as the wavelength shortens below 10 cm)

Respuesta :

Answer:

20k hz

Explanation:

Frequency of the sound at which the wavelength is equal to the distance between a pair of human ears. Thus, the frequency is 62.8 Hz.

What is frequency?

Frequency is the no of cycles per second. It is related to wavelength as

f = 2π / λ

Substitute the value of wavelength λ =10 cm = 0.1 m

f = 2 x 3.14 / 0.1 m

f = 62.8 Hz

Thus, the frequency is 62.8 Hz.
