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. Science Lab Supplies manufactures it in Saha, Ambala (Plot 448, HSIIDC Industrial Area) and sells direct to schools, colleges, tender contractors and distributors.
Specifications
The apparatus is built around a brass pipe that forms the resonating air column; brass is used for durability under repeated classroom and laboratory use. It works with standard tuning forks, 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 standard 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 a resonance tube and two resonance positions.
- The relationship between frequency and wavelength, using forks of different frequency.
- B.Sc. physics: end correction and standing waves in a resonating air column.
- Teacher demonstrations of resonance in air columns for Class 9 sound lessons.
Standard Scope of Supply
The Resonance Apparatus Brass Pipe is supplied as a single unit as described above. Tuning forks and any supporting components for your chosen model are listed separately on the quotation, so you can see what will be packed.

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?
Tuning forks are listed separately on the quotation. 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?
Science Lab Supplies is the manufacturer. The resonance apparatus comes from its works in Saha, Ambala, where this science apparatus manufacturer in India also handles pricing and dispatch.
