Resonance tube apparatus of variable length \(L\) with one closed end and one open end.
Resonance tube apparatus of variable length \(L\) with one closed end and one open end.
A student performs an experiment to determine the speed of sound in air using a resonance tube of adjustable length \(L\) that is closed at one end and open at the other. A small speaker positioned near the open end is adjusted to find the fundamental resonant frequency \(f\) for several different tube lengths. Which quantities should be plotted on the vertical and horizontal axes to yield a straight line, and how should the slope \(S\) of the best-fit line be used to determine the speed of sound \(v\)?
