About This Product
The resonance tube experiment finds the wavelength of a known note using a column of air. A tuning fork sounds over the mouth of the tube while the water level is changed, and the sound grows loud at the lengths where the air column resonates. The first resonance occurs at about a quarter of a wavelength, and the next one half a wavelength further along. Measuring these lengths gives the wavelength, and with the frequency of the fork the speed of sound follows. Alongside supply within India, the Resonance Apparatus is offered for export to Antigua and Barbuda, Seychelles, Mexico, Djibouti, Jordan and Sudan.
Frequently Asked Questions
Q1. What is included with the Resonance Apparatus?
It has a 1 m vertical stand with a metric scale, a 20 mm plastic tube connected to a 1 L vessel of water, and a tuning fork.
Q2. How is the water level changed?
The vessel is raised or lowered, which adjusts the water level in the tube.
Q3. How is resonance found?
Listen at the mouth of the tube while the level is adjusted, then mark the air column lengths where resonance is evident.
