## Homework Statement

How can i find the fundamental frequency of a closed piep (measuring cylinder) experimentally/ physicaly. I have done the maths and found the frequency but i want another way to prove this other than simply playing the calculated frequency back at the measuring cylinder. I have heard of a method called overblowing or Helmholtz frequency and using a program named Audacity to find it but after further research, i think Helmholzt frequency can only be used on bottles where there is a "neck" or part with a smaller diameter at the top. Can i use Helholzt frquency/ overblowing?
