An
investigation of the driven harmonic oscillator, showing the measured
oscillator amplitude as a function of drive frequency. These data
were taken by hand in about 15 minutes, observing the length of the
laser streak on the graduated ruler. The fit curve is a Lorentzian, which is a reasonable approximation of the theoretical
response function of a Simple Harmonic Oscillator. Residuals show the
data minus the fit curve, scaled to give the residuals in percent of
the measured amplitude.
