Question

A sound is traveling through the air with a temperature of 35•C. The sound wave has a wavelength of 0.75 meters. What is the frequency of the sound

Answer 1

f = 687.85 Hz

Step-by-step explanation:

Given that,

The wavelength of sound wave,
`\lambda=0.75\ m`

We need to find the frequency of the sound wave. The relation between wavelength and frequency is given by :

`v=f\lambda`

v is speed of sound at T = 35°C = 308.15 K

`v=331+0.6T\\\\v=331+0.6* 308.15 \\\\v=515.89\ m/s`

So,

`f=(v)/(\lambda)\\\\f=(515.89)/(0.75)\\\\f=687.85\ Hz`

So, the frequency of the sound is 687.85 Hz.
