- Interaction of radiation from more than one source, but of a single wavelength, to produce a stationary wave pattern called an interference pattern. The pattern is bright where the waves add and dark where they subtract. Interference patterns contain information about the detailed structure of emissions in visible or other wavelengths of electromagnetic radiation and can be used to provide details of the structure of materials on the scale of the wavelength of light, e.g. the optical accuracy of a telescope mirror. A familiar example is a Moiré (e acute) pattern.
