Savarts toothed wheel, Nairobi Industrial Area

Savart's toothed wheel is a scientific apparatus designed to demonstrate the principles of sound and vibration. It features a large wheel with evenly spaced teeth around its circumference, mounted on a spindle for smooth rotation. Typically constructed from durable materials like wood or metal, the wheel produces a series of musical tones as it spins, with the frequency of these tones determined by the speed of rotation and the spacing of the teeth. This apparatus is particularly effective in educational settings, allowing students to visualize sound waves through the use of sensitive microphones or oscilloscopes. Named after the French physicist Hippolyte Savart, it serves as an engaging tool for illustrating the connection between mechanical motion and sound, making it a staple in physics and music education.
