Question

The note a4, above middle c has a frequency of 440 hz. sounds travels at about 340 m/s. what is the wavelength of middle a?

Answer 1

Wavelength of wave is 0.7727 m .

Explanation:

Given :The note a4, above middle c has a frequency of 440 hz. sounds travels at about 340 m/s.

To Find: what is the wavelength of middle a?

Solution:

We are given that The note a4, above middle c has a frequency(f) of 440 hz .

Velocity of wave (c) = 340 m/s

Formula of wavelength:
`\lambda = (c)/(f)`

So , wavelength =
`(340)/(440)`

=
`0.7727`

Thus the wavelength of wave is 0.7727 m .
