You are playing a pipe organ, with pipes that are designed to be closed at one end, when you notice that one of the notes sounds wrong. You soon discover that one of the pipes has a hole in the end that was supposed to be closed.
(a) After you patch up the hole, what will happen to the frequency of the note played by this pipe? Be as specific as possible.
(b) What else can you do to “tune” an organ pipe (i.e. change the frequency of the notes it plays) without altering the physical construction of the pipes? Indicate how you could increase the frequency of the note and also how you could decrease the frequency of the note.
The Attempt at a Solution
My guess is that the frequency would increase with the hole closed up, but I'm not sure how to explain that. For the second question, I was thinking changing the room temperature would affect the speed, which in turn would affect the frequency, since the wavelength should remain the same.
