You and a friend have some pvc pipes of various lengths and a hacksaw. You select a 2.0 m long section of pipe that is open at both ends but your friend chooses a 0.60 m long section of pipe that is closed at one end. You want to cut your open pipe to a length that makes its no = 2 harmonic the same frequency as the closed-at-one-end pipe’s nc = 3 harmonic. How long should you make your pipe?
