Iridescence L’iridescence (aussi connu sous le nom de goniochromisme) est la propriété de certaines surfaces qui semblent changer de couleur selon l'angle de vue ou d'illumination. Des exemples d'iridescence comprennent notamment : les bulles de savon, les ailes de certains papillons, certains coquillages et certains minéraux. L'iridescence est souvent créée par une coloration structurelle de microstructures qui interfèrent avec la lumière.

| Résumé : |
The meaning of iridescent is, showing luminous colours that seem to change when seen from different angles. "The drake's head has an iridescent purple sheen" also known as shimmering , shimmery, glittering, sparkling, coruscating, dazzling, gleaming, glowing, lustrous, scintillating, opalescent, opaline, multicoloured, rainbow like or rainbow coloured. Paints made using such pigments exhibit such properties. Iridescente (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change colour as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, butterfly wings and seashells, as well as certain minerais. Iridescente, 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 colour. Constructive interference is what happens in iridescence. It causes the two waves to complement each other and strengthen the reflection. Basically, when the crests and troughs of more than one wave of light match up, their powers are magnified. When they do not match up, they are mostly destroyed.
The iridescent and interference colours achieve their reflective properties by synthetically reproducing several natural phenomena - the nacreous, or pearlescent, qualities found in fish scales or the dust of a butterfly's wing, and the shiny and reflective qualities found in certain metals and minerals. |
