Q A: What Causes Iridescence? – Yale Scientific Magazine Many colors found in nature are produced by pigmentation, which simply absorbs certain wavelengths of light and reflects others Iridescence, however, occurs when an object’s physical structure causes light waves to combine with one another, a phenomenon known as interference
IRIDESCENCE Definition Meaning - Merriam-Webster The meaning of IRIDESCENCE is a lustrous rainbowlike play of color caused by differential refraction of light waves (as from an oil slick, soap bubble, or fish scales) that tends to change as the angle of view changes
Iridescence - National Museum of Asian Art The color shifts of iridescence can be dramatic, as in precious opals, or subtle, as in a beetle wing, a kingfisher feather, or the corrosion on a glass Several different phenomena can cause iridescence, and regardless of how it is created, it always remains captivating
Iridescence: a functional perspective - PMC - PubMed Central (PMC) Iridescent coloration is broadly distributed in the animal kingdom and appears to have evolved independently in a number of different taxonomic groups Iridescence is a relatively common feature in some groups of invertebrates, particularly arthropods and molluscs
Iridescence - an overview | ScienceDirect Topics Iridescence means a change in structural color upon a change in the viewing angle Color is of utmost importance for living organisms; it allows camouflage and sexual recognition and helps to control the body temperature in the case of poikilotherms
Iridescence | Causes of Color - WebExhibits Iridescence in the animal kingdom Structural colors occur naturally in a rich variety of systems, usually involving multiple-layered structures that provide thin-film interference The layers may be composed of keratin, chitin, calcium carbonate, mucus, and so on
Iridescence vs. Opalescent — What’s the Difference? Iridescence is a phenomenon where an object's surface appears to gradually change color as the angle of view or illumination changes, while opalescent refers to objects exhibiting a milky iridescence like that of an opal
