Q: Do resonance positions get harder to find lower down in the tube?
Note: this is a questions based on a physics lab revolved around the idea of sound waves and the measurement of the velocity of sound in an air at room temperature and understanding the meaning of longitudinal or compressional waves. A synopsis of the lab: basically we used a long glass tube filled with water and attached to the apparatus was a reservoir in which as we brought lower to the ground water would fill it and the water in the tube would decrease, a sound of a certain frequency using a speaker would be continuously playing directly down the tube from the mouth and we had to tick off 5 times the depth in when we would hear the sound frequency change as the water level was lowered.
Thanks for helping!
