# When the speed of sound is 340 m/s, what is the wavelength (in m) of a 750 Hz sound?

## Question:

When the speed of sound is 340 m/s, what is the wavelength (in m) of a 750 Hz sound?

## Wavelength of a Sound Wave:

The wavelength of a sound wave is measured using the sound's speed and frequency, and it is defined using the below equation.

{eq}v = f\lambda {/eq}

Here, the frequency is {eq}f, {/eq} and the sound wave's speed is {eq}v {/eq}, and the wavelength is {eq}\lambda {/eq}.

Similarly, we define the frequency considering the speed and wavelength of a sound wave.
