About This Product
A sound tube is spun in the air to produce musical notes. The notes rise in steps rather than smoothly because the air in the tube can resonate only at certain harmonic frequencies, which is a standard example of standing waves. Teachers use it to link pitch with frequency and to show that resonance depends on the shape of the air column. Students can count the distinct notes as the speed increases. Schools, colleges and distributors in Zambia, Mongolia, Brunei, Malaysia and Chad can source the Sound Tube from School Lab Equipment India.
