Speed of Sound

In class demonstration of a "woohoo" tube by professor Mason.

With a sealed one end, the tube was quickly spun and the sound it emitted was recorded on Logger Pro.



Since one end is sealed, the resulting sound is made by a harmonic wave, which is a wave that is a multiple of a fundamental wave.
