Question

A sound wave with a wavelength of 2.5 m travels 660 m in 2 s. Calculate the frequency of the wave. (To calculate the speed of sound, remember: speed = distance/time.)

Answer 1

`f = 132\,hz`

Step-by-step explanation:

The speed of the sound wave is:

`v = (660\,m )/(2\,s)`

`v = 330\,(m)/(s)`

The frequency is:

`f = (v)/(\lambda)`

`f = (330\,(m)/(s) )/(2.5\,m)`

`f = 132\,hz`
