Lascells Resonance Tube

This apparatus is ideal for all resonance investigations in air columns.
The main tube is 1 metre long and 50mm diameter with a high power loudspeaker unit plugged in to one end. The loudspeaker is driven by a standard laboratory signal generator and as the frequency is adjusted the various resonance modes are detected by increased loudness of the note.
The open pipe can be studied or a variable length closed pipe can be used by inserting the piston assembly provided. By using a higher amplitude on the generator, Kundt’s tube investigations can be undertaken. Fine cork or polystyrene dust is distributed throughout the tube and at resonance the powder gathers at the nodes. Wavelengths can be easily measured.
To get a good response a closed tube is preferable, to reduce the sound levels in the laboratory while producing a measurable effect.
The apparatus comes complete with two supports for the tube, sound wave generator, resonance tube, closing bung and full instructions.
Requires a signal generator.
