Abstract
The speed of sound in air is typically known for any given temperature and can be verified in a tube with a constant radius by measuring the resonant frequencies which are a harmonic sequence that is linearly related to sound velocity. We can measure those frequencies using a microphone, sound generator, and lock-in amplifier. However, when this relationship is used, the speed of sound found is much lower than the speed measured when sound travels through a tube with varying radii. This indicates to us that our equation needs to be altered to compensate for the varying radii. By testing a variety of tubes of different length and radius we can compare different theoretical methods and determine which method is best.
