Homework Statement
I have 8 pipes for a school project taped together to make a pan flute, they are 7, 9, 11, 13, 15, 17, 19, 21 inches... 1 inch diameter each one. I have to find the frequency of each one, but I'm not sure what the Harmonic numbers are. It is an open-ended instrument. I plan to use as a percussion instrument, using my hand, hitting the ends of the pipe to create sound.
Homework Equations
F = Hn * V/2L
F: frequency
Hn: Harmonic number
V: speed of sound traveling through pipe assume 343 m/s
L: length of pipe sound is traveling through
The Attempt at a Solution
I'm not sure how, as I do not know how to find the harmonic number, my teacher just gave us a project to make a pvc pipe instrument and a formula for Open-ended, stringed, and closed instruments. The teacher does not expect questions on anything...
Not sure how to attempt without harmonic numbers...
