Resonance Tube Set
Product Code : EL-PLE-11894
Quick Answer: The Resonance Tube Set is a 1 m long, 50 mm diameter tube with a sound wave generator unit and a piston assembly, used for resonance tube experiments on open and closed air columns. It is driven by a standard laboratory signal generator, which is ordered separately.

Key Features
- Main tube 1 m long and 50 mm in diameter, held on two supports.
- High-power sound wave generator unit plugs into one end of the tube.
- Piston assembly turns the open pipe into a variable-length closed pipe.
- Resonance modes are found by adjusting the signal generator frequency and listening for the louder note.
- At higher amplitude the tube can be used for Kundt's tube work with fine cork or polystyrene dust.

About This Product
The set is used for sound wave experiments on resonance in air columns. The open pipe can be studied, or the piston can be inserted to vary the length of a closed pipe. When fine dust is spread along the tube at resonance, it gathers at the nodes, so the wavelength can be measured directly. A closed tube gives a good response at lower sound levels in the laboratory. The Resonance Tube Set can be exported to customers in Portugal, Saint Vincent and the Grenadines, the Solomon Islands and Egypt.
Frequently Asked Questions
Does the Resonance Tube Set include a signal generator?
No. The sound wave generator unit is included, but it must be driven by a standard laboratory signal generator, which is ordered separately.
Can it be used for Kundt's tube experiments?
Yes. With a higher amplitude on the generator, fine cork or polystyrene dust spread through the tube collects at the nodes at resonance, and the wavelength can be measured from the spacing.
Is an open or a closed tube better?
Both can be studied. A closed tube, made by inserting the piston, is preferable for a good response because it keeps the sound level in the laboratory lower while still giving a measurable effect.
