Experimenting with end-correction and the speed of sound

摘要

What follows is an alternative to the standard tuning fork and quarter-wave tube speed of sound experiment. Rather than adjusting the water level in a glass or plastic tube to vary the length of an air column, a set of resonance tubes of different lengths is used. The experiment still demonstrates the principles of standing waves in air columns and can also be used to study end-correction as well as determining the speed of sound in air.
