For this question, we're told that a standing wave is contained within a pipe closed at both ends. We're also given the wavelength for the fifth harmonic, and are asked to find the length of the pipe.
The first step to solve this problem is to use the equation for a pipe closed at both ends.
Since we're told which harmonic the wave is on, as well as its wavelength, we have everything we need to solve for the length of the pipe.

. If the pipe is open at both ends, what is the frequency of the third harmonic assuming that the velocity in which sound moves through the air is 
.
A pipe has a length of
Tap to reveal answer
Since the pipe is open at both ends, we can use the equation 
where f is the frequency we are solving for, 
is the number of the harmonic, 
is the velocity at which sound moves through air, and L is the length of the pipe.
We know from the question that:
When we plug in these values into the frequency equation, we get 
as the answer.
