# Homework Help: Determining overtones of sound waves in a pip

1. The problem statement, all variables and given/known data
Standing sound waves are produced in a pipe that is 1.60 {\rm m} long. 1) the pipe is closed at the left end and open at the right end , determine the locations along the pipe (measured from the left end) of the displacement nodes for the first overtone. 2) If the pipe is closed at the left end and open at the right end , determine the locations along the pipe (measured from the left end) of the displacement nodes for the second overtone.

2. Relevant equations

3. The attempt at a solution
I got the first four questions to this set regarding pipes opened at both ends, but can't figure this out. Does anyone have an easy solution? I need to know how to do this for my test. Thanks!

Re: Pipes

In the closed pipe, during resonance, always anti node appears on the open end and node appears at the closed end. Can you find out the number of nodes between the extreme ends during first and second over tones?

Re: Pipes

Can you explain overtones?
