Resonance Tube Set
Product Code : JL-LEP-10428
The Resonance Tube Set (SKU JL-LEP-10428) varies the length of an air column to produce resonance of sound from a loudspeaker or tuning fork. This resonance tube has a 50 mm inner tube with a permanent millimetre scale sliding inside a 63 mm outer tube with felt air sealing, on a stand that holds it 52 mm above the bench in line with the loudspeaker. Students use it to find the wavelength and speed of sound in air. JaincoLab manufactures it in India.
Specifications
The set consists of a 63 mm OD outer tube at least 1030 mm long with a detachable rubber plug, a 50 mm OD inner tube 1100 mm long with a permanent 1 mm scale, felt-cloth sealing and a fixed plastic stopper, and a rigid stand that places the tube centre 52 mm above the surface.

Applications of the resonance tube
A tuning fork or loudspeaker sounds at the open end while the inner tube is slid out; the air column resonates loudly at particular lengths, which students read off the scale to calculate wavelength and the speed of sound.
- Finding the first and second resonance lengths for a tuning fork
- Calculating the wavelength and speed of sound in air
- Repeating the experiment at several frequencies with a tone generator and loudspeaker
- Estimating the end correction of the tube
- Sound and resonance practicals in senior secondary and college physics

Frequently asked questions
How does the resonance tube work?
Telescoping tubes change the length of the air column until it resonates with the sound source.
What are the tube sizes?
The outer tube is 63 mm OD and at least 1030 mm long; the inner tube is 50 mm OD and 1100 mm long.
How is the length read?
From a permanent 1 mm scale on the inner tube that resists rubbing and fading.
Which sound sources can be used?
Tuning forks, or a loudspeaker driven by a tone generator.
What should a quotation request include?
Send the SKU JL-LEP-10428, the number of sets and the delivery destination.
