Triggered by a moment of insight thirty years earlier, this theory explains how harmonics combine to form coherent geometrical patterns that our auditory system recognizes as simple shapes. ... Using a spectral analysis of harmonic interference over an octave, the author shows how ... Harmonic Interference Theory...

Interference Theory [Back] ... This is called constructive interference. However, if the two waves are out of phase by just one half ... of the wavelength, they add together such that they cancel each other out, and the result is a zero intensity. This is called destructive interference, and is shown below.

Theory of Interference; (Fabry-Perot Etalon) ... Consider light from a monochromatic point source of wavelength which passes through a large circular aperture (so large that diffraction effects are negligible) and is incident upon a Fabry-Perot etalon.

Theory of Interference; (Michelson Interferometer) ... Consider light from a monochromatic point source of wavelength incident upon a Michelson interferometer. (See any of the still pictures from this module to see the setup.) The interferometer works in the following way.

Thomas Young was one of the first to design a method for producing such an interference pattern. He allowed a single, narrow beam of light to fall on two narrow, closely space slits. Opposite the slits he place a viewing screen.
