146 Sound Resonance in a Tube Overview Sound waves are considered longitudinal waves. That is, the molecules (air molecules for instance) will oscillate about their equilibrium positions in the direction of the wave (disturbance). If a tuning fork vibrates and held over an open ended tube, which is closed at the bottom, it will send a sound wave down the tube. This...

A resonance tube can be used to measure the speed of sound in air. A tuning fork is held above the opening of the tube and struck, while the far end of the tube is lengthened or shortened. Resonances (loudnesses) are heard at a series of tube lengths, L, which are carefully measured. resonance tube The speed of sound in air is determined by measuring the distance between two consecutive resonances. A data set for a tuning fork with a...

Q6. (1) Using the measured speed of sound from longer pipe, estimate the temperature of the lab room, with uncertainty. The speed of sound is given by v 331 +0.6T (m/s), where T is the temperature in degrees Celsius. Does this find the lab room to be significantly warmer or colder than room temperature (say, 20+20C)? Justify using your uncertainties. Also, does this result make sense? Does...

The speed of sound in room temperature (20?C) air is 343 m/s; in room temperature helium, it is 1010 m/s. The fundamental frequency of an open-closed tube is325Hz when the tube is filled with air. What is the fundamental frequency if the air is replaced with helium?

A long cylindrical gas-tight tube, with a sound source at one end and sensor at the other
1. A long cylindrical gas-tight tube, with a sound source at one end and sensor at the other, was constructed to measure the speed by recording the time it take a sound wave to travel the length of the tube (see diagram). i. Initially, the tube was filled with air at atmospheric pressure (P=1.012x105Pa & T=295.2K). When a sound wave is produced by the source, the elapsed time for the wave to reach the sensor was 3.64x10-3s. Determine the length of...
