Formula: Kundt's Tube
Standing Waves in a Kundt's Tube

Tube length

The tube can only have certain lengths so that a standing wave is formed in the tube.


Wavelength of the acoustic sound directed into the tube.

Number of nodes

A natural number \( \class{red}{n} = 0, 1, 2, \ldots \) that specifies the number of vibration nodes and defines the possible lengths of the tube.
