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