Question

The speed of sound in a particular gas is 675 m/s. A sound wave propagating in this material has a wavelength offifteen meters. What is the frequency of this sound?knowns and unknownsolveright answer

Answer 1

Given, Speed of the sound, v=675 m/s

The wavelength of the wave, λ=15 m

Relation between speed, wavelength, and frequency of a wave is given by

`v=f\lambda`

Where f is the frequency of the sound.

On substituting the known values,

`675=f*15`

Which gives us,

`f=(675)/(15)=45\text{ Hz}`

Therefore the frequency of the sound in the given medium is 45 Hz.
