Question

The wavelength of a sound wave was measured to be 0.782 m. If you know that the speed of sound in air was 343 m/s, then determine the frequency of the sound wave.

Answer 1

Frequency of the sound wave will be 438.61 Hz

Step-by-step explanation:

We have given wavelength of the sound wave
`\lambda =0.782m`

Speed of the sound wave v = 343 m/sec

We have to find the frequency of the sound wave

We know that speed of the sound wave is given by
`v=\lambda f`, here v is velocity,
`\lambda` is wavelength and f is frequency

So frequency f
`=(v)/(\lambda )=(343)/(0.782)=438.61Hz`
