About This Product
A Quincke tube splits a sound wave into two paths and brings them together again. When the length of one path is changed, the two components add or cancel, and a microphone records the resulting maxima and minima. From the change in tube length between successive minima, students find the wavelength and then calculate the frequency. The experiment links wavelength, frequency, interference and phase shift with the velocity of sound in air. Schools, colleges and distributors in Colombia, Lebanon, Malta, Guinea and Uganda can source the Wavelengths and Frequencies with a Quincke Tube from School Lab Equipment India.
Frequently Asked Questions
Q1. What does the Wavelengths and Frequencies experiment demonstrate?
It shows how a sound wave divided into two coherent components produces interference when the path of one component is altered, so that the wavelength and frequency can be calculated from the interference recorded with a microphone.
Q2. Which frequency range is used?
The tasks use given frequencies in the range 2000 Hz to 6000 Hz, recording the extension of the Quincke tube for each.
