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 #lambda#:

#lambda = v/f#

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

#lambda = (340m/cancels)/(440cancels^(-1))#

#lambda = 0.773 m#
