(1) Measure and record the length and diameter of the tube in the table (2) Connect the microphone to the interface. Note: of the several overlapping waves present (pres sure, displacement, density), a microphone measures the sound pressure wave Ap. (3) Open file \"Experiment-11-standing-waveresonances" (4) In \"Experiment\" tab change data collection duration to 0.05 s and record the background signal (5) Enable triggering [from Tab \"Data Collection\"] at a value slightly higher than the level of the background signal and start data collection. There should be no signal recorded yet on the computer screen. (6) Set sampling rate to 20,000 samples/ second (7) Position the tube near the microphone and strike one end of the tube with your nger. This is the case of a tube open at both ends. Once you are satised with the wave appearance, store it. (8) Strike one end of the tube with your palm. This is the case of a tube closed at one end. Once you are satised with the wave appearance, store it
