The problem of the wave on a string is a typical problem in general physics.  This experiment starts by considering the resonant frequencies of a rigid rod.  Since the ratios of the overtones to the fundamental are not integers, the overtones are not called harmonic.  Rather, they are called enharmonic.  We would expect to see waveforms analogous to the wave on the string or closed pipe resonator.  For the fun of it, we will proceed onto a thin rod in the form a hoop, with the expectation of seeing standing waves that are analogous to Bohr atom-like results (see picture on experiment's main page and hoop photos).

    The hope is that there is some connection between this one dimensional problem and the two dimensional problem of Chladni plates.
