Wavelengths and frequencies with a Quincke tube with digital function generator

Product No: P2150702

Principle

When a sound wave of a particular frequency is divided into two coherent components (like, for example, light waves in an interferometer experiment), and if the path of one of the component waves is altered, it is possible to calculate the wavelength of the sound wave and its frequency from the interference phenomena recorded with a microphone.

Tasks

Record the extension of a Quincke tube for given frequencies in the range 2000 Hz to 6000 Hz.
Calculate the frequencies from the wavelengths determined and compare them with the given
