Introduction to Fourier Optics
Huggins, Elisha
Physics Teacher, v45 n6 p364-368 Sep 2007
Much like a physical prism, which displays the frequency components of a light wave, Fourier analysis can be thought of as a mathematical prism that can tell us what harmonics or frequency components are contained in a recording of a sound wave. We wrote the MacScope II program so that the user could not only see a plot of the harmonic amplitudes but also see the harmonic waves and how these waves add together to recreate the original sound curve.
