Iridescence (also known as goniochromism) 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.

Iridescence, however, occurs when an object’s physical structure causes light waves to combine with one another, a phenomenon known as interference. In constructive interference, light waves combine so that the crests and troughs line up to reinforce each other, increasing the vibrancy of the reflected color.

Iridescence is explained by assuming that light is a wave. Maxwell's theory describes light has having electric and magnetic properties--electromagnetic waves. It is an improvement over the wave theory in that it explains how light is generated. Visible light is only one type of electromagnetic wave.

Iridescent colours have been fascinating to humans throughout history; they are flashy, shimmering, dynamic, and examples surround us, from the commonly seen iridescent sheen of oily street puddles to the exotic, gaudy displays of birds-of …

Iridescence is an optical phenomenon that occurs when light is reflected off a surface in such a way that it appears to shift in color as the angle of view changes. But is iridescence actually considered a distinct color itself?

Iridescence separates the spectral colors present in white light. The colors of iridescent materials gradually change as the viewing angle changes. Iridescent colors are generated by the structure of objects, not by the presence of colored pigments, thus they are structural colors. Light reflected by multiple layers or particles, its ...

For example, light waves can interfere with one another, causing the iridescent colors you see in a layer of oil on a wet pavement or in the surface of a soap bubble. Other examples of iridescence caused by interference include ice and crumpled cellophane, which will produce iridescent colors in polarized white light.

2024年5月25日 · Iridescent light is a type of light that appears to change color when viewed from different angles.

2024年10月1日 · Iridescent glass can enhance a building's energy efficiency by reducing heat gain through selective light transmission and reflection, lessening the need for artificial lighting and cooling. Its dynamic responses to sunlight can optimize natural illumination while minimizing energy consumption for climate control systems.
