Answer:

The sound wave has a wavelength of 0.773m.

Explanation:

To solve this problem we have to use the wave equation that is given below:

We know the frequency and the velocity, both of which have good units. All we have to do is rearrange the equation and solve for λ:

λ=vf

Let's plug in our given values and see what we get!

λ=340ms440s−1

λ=0.773m
