Title: Iridescence Authors: Venue: Wikipedia Year: unknown Canonical: wiki:iridescence URL: https://en.wikipedia.org/wiki/Iridescence Collector: wikipedia OA: true ABSTRACT Iridescence is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes. Iridescence is caused by wave interference of light in microstructures or thin films. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and the mineraloid opal. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects.
