Acoustic resonance apparatus
Product Code : SCL-ES-12778
Quick Answer: The Acoustic Resonance Apparatus is used to find the velocity of sound in air from the resonance of an air column driven by a tuning fork. The air column length is adjusted by hand until the loudest sound marks a resonance point.

Key Features
- Resonance tube with a manually adjustable air column
- A tuning fork of known frequency held at the open end drives the air column
- The loudest sound marks each resonance position
- Air column lengths at resonance give the wavelength and the velocity of sound in air
- Used with tuning forks, a rubber hammer, measuring scale, water reservoir and stand

About This Product
Resonance happens when the natural frequency of the air column matches the frequency of the tuning fork, so the sound swells noticeably. Recording the column length at one or two resonance points lets students calculate the wavelength and then the speed of sound. The Acoustic resonance apparatus can be supplied on export terms to Burundi, South Korea, Oman, Slovenia and Burkina Faso.
Frequently Asked Questions
How is resonance found with the Acoustic Resonance Apparatus?
Strike a tuning fork of known frequency with the rubber hammer, hold it near the open end of the tube and slowly change the water level or air column length. The loudest sound marks resonance; record that length.
