Open and closed organ pipes
Choose a pipe type and harmonic. See the standing wave of air displacement inside the pipe.
What to notice
A closed pipe has a node at the closed end and supports only odd harmonics.
Key relation
Open: fₙ = nv/2L ; Closed: fₙ = (2n − 1)v/4L
Try this
Compare the fundamental of an open and a closed pipe of the same length.
What you can change
- Pipe: choose Open at both ends, Closed at one end
- Pipe length: 0.2 to 2 m
- Harmonic number n: 1 to 5
- Air temperature: 0 to 40 °C
