Unformatted text preview: Standing sound waves Standing sound waves Sound in fluids is a wave composed of longitudinal vibrations of molecules. The speed of sound in a gas depends on the temperature. For air at room temperature, the speed of sound is about 340 m/s. At a solid boundary, the vibration amplitude must be zero (a standing wave node ). node node node antinode antinode Physical picture of particle motions (sound wave in a closed tube) graphical picture Standing sound waves in tubes – Boundary Conditions-there is a node at a closed end-less obviously, there is an antinode at an open end (this is only approximately true) node antinode antinode graphical picture Exercise: Sketch the first three standing-wave patterns for a pipe of length L, and find the wavelengths and frequencies if: a) both ends are closed b) both ends are open c) one end open L a) Pipe with both ends closed L b) Pipe with both ends open L 1 4 1 λ = L 3 4 3 λ = L 5 4 5 λ = L c) Pipe with one closed end, one open end Beats Chap 18...
