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...

A closed tube of length 0.60 m is used to create a standing sound wave. Assume that the standing wave created in the tube has the second longest wavelength possible (out of all possible standing waves that fit in the tube). If this tube is then placed on a truck that moves away (at a speed of 90.0 km/hr) from a stationary observer, what frequency does the observer hear?

A 0.75m long instrument tube has two open sides as a standing sound wave moves through it (speed of sound is 343 m/s). You count 4 nodes in the tube. (a) Find the wavelength and frequency. (b) You suddenly close both ends of the tube. The number of nodes doesn't change, but their positions do What is different about the air pressure and displacement? How did the wavelength and frequency change?

A sound wave in air has a pressure amplitude equal to 4.04 ✕ 10-3 Pa. Calculate the displacement amplitude of the wave at a frequency of 9.4 kHz. (Note: Use the following values, as needed. The equilibrium density of air is ρ = 1.20 kg/m3; the speed of sound in air is v = 343 m/s. Pressure variations ΔP are measured relative to atmospheric pressure, 1.013 105 Pa.)
