Hear and see resonance

The Resonance Tube apparatus offers an affordable and easy-to-use solution for studying resonance in open and closed pipes—letting students both hear and see resonance in action. By varying the length of the closed tube with the included plunger, students can investigate standing sound waves and resonance modes firsthand. Add cork or polystyrene dust to visualize the resonant waveforms, transforming the apparatus into a Kundt’s tube and making abstract wave concepts concrete and measurable.

Why Teachers Love the Resonance Tube

Hear and SEE resonance: Increased sound intensity reveals resonance while cork or polystyrene dust gathers at nodes for visual confirmation.
Open and closed pipe studies: Easily switch between open-pipe and variable-length closed-pipe investigations.
Adjustable and precise: The piston assembly allows smooth changes in tube length for accurate wavelength measurements.
Complete, classroom-ready apparatus: Includes tube supports, sound wave generator unit, closing bung, and full instructions.
