Product Code : SCL-PL-12132
Resonance Apparatus Brass Pipe (SKU SCL-PL-12132) is a resonance tube for studying standing sound waves in an air column. A tuning fork is sounded at the open end while the air column length is adjusted until the sound is loudest, giving the wavelength and the speed of sound in air. It serves Class 11 and college practicals. The apparatus is manufactured at Plot 448, HSIIDC Industrial Area, Saha, Ambala, where Science Lab Supplies prices it for schools, colleges, tender contractors and distributors.
Specifications
The brass resonance pipe is summarised row by row below. In short, a brass pipe forms the resonating air column, chosen for durability under repeated classroom and laboratory use; it works with tuning forks of known frequency, and the air column length is adjusted during the experiment to find each resonance point.

Applications and Experiments for the Resonance Apparatus
The resonance tube is the classic route to the speed of sound in school and college labs: find the air column lengths at which a known tuning fork resonates, calculate the wavelength, and multiply by the frequency. It also shows standing waves, nodes and antinodes in air.
- NCERT Class 11 physics practical: speed of sound in air at room temperature using two resonance positions, with the room temperature read on one of the alcohol-filled Laboratory Thermometers.
- The relationship between frequency and wavelength, using forks of different frequency.
- B.Sc. physics: end correction and standing waves in a resonating air column, with the pipe’s inner diameter taken on a Vernier Caliper.
- Teacher demonstrations of resonance in air columns for Class 9 sound lessons.
Standard Scope of Supply
Each order covers the brass pipe resonance apparatus with the supporting laboratory components of the selected model, product packaging and its instruction documentation. Whether tuning forks come with your chosen model is confirmed on the quotation, which also itemises any forks or other sound apparatus you add.
Packing, MOQ and Lead Time
A quotation can cover a single apparatus or a full set for a physics practical room, with packing, delivery time and price stated for that quantity. Tuning forks and other items from the physics lab equipment list for Class 11 and 12 can be added to the same quotation.

Frequently Asked Questions
What is the resonance apparatus used for?
It is used to study resonance in an air column and to find the wavelength and the speed of sound in air from the resonating lengths produced by a tuning fork of known frequency.
Why is the pipe made of brass?
Brass gives a durable pipe that stands up to repeated classroom and laboratory use, so one apparatus can serve batch after batch of students.
Are tuning forks included?
The components can vary with the model chosen, so the quotation confirms whether forks are part of it. Tell us through the contact page which frequencies your practical uses, and they can be quoted with the apparatus.
Is Science Lab Supplies the manufacturer or a trader?
This brass pipe apparatus is made at the company’s own works in Saha, Ambala, where pricing and dispatch are also handled, so buyers deal with Science Lab Supplies as the manufacturer and not with a trading house.
