1. The problem statement, all variables and given/known data The Lowest note on an organ is 16.4 Hz. a. What is the shortest pen organ that will resonate at this frequency b. What is the pitch of the same organ pipe is closed 2. Relevant equations f=V(n)/2L, n=1,2,3.. f=V(n)/4L, n-1,3,5... 3. The attempt at a solution I understand how to do this problem , such as setting up the equation as 16.4=V(1)/2L and solve for V then you should get 16.4Hz= 32.8L/2L, but with that any L short of zero can work. I am thinking that there is not enough information to solve this problem anyone else have an idea?
