Please help me draw a schematic diagram, write down the original formula, and have a detailed procedure

You and a friend have some common pvc (polyvinyl chloride) 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 closedatone end pipe's nc = 3 harmonic. How long should you make your pipe? For the representation, draw each section of pipe with its appropriate standing wave, making sure that the wavelengths of each section match
