Optical phenomena are any observable events that result from the interaction of light and matter. All optical phenomena coincide with quantum phenomena. [ 1 ] Common optical phenomena are often due to the interaction of light from the Sun or Moon with the atmosphere, clouds, water, dust, and other particulates.
In addition to the gestalt principles of perception, water-color illusions contribute to the formation of optical illusions. Water-color illusions consist of object-hole effects and coloration. Object-hole effects occur when boundaries are prominent where there is a figure and background with a hole that is 3D volumetric in appearance.
Opalescence or play of color is an optical phenomenon associated with the mineraloid gemstone opal, [1] a hydrated silicon dioxide. [2] This effect appears as a milky, translucent glow that changes with the angle of light, often creating a soft, pearly sheen that can display various colors or hues.
The Kanizsa triangle is an optical illusion first described by the Italian psychologist Gaetano Kanizsa in 1955. It is a triangle formed of illusory contours. Kinetic Depth Effect: The Kinetic depth effect is the phenomenon whereby the three-dimensional structural form of a silhouette can be perceived when the object is moving. In the absence ...
For example, a white page under blue, pink, or purple light will reflect mostly blue, pink, or purple light to the eye, respectively; the brain, however, compensates for the effect of lighting (based on the color shift of surrounding objects) and is more likely to interpret the page as white under all three conditions, a phenomenon known as ...
Blue–red contrast demonstrating depth perception effects 3 Layers of depths "Rivers, Valleys & Mountains". Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images.
Art historians say Leonardo da Vinci hid an optical illusion in the Mona Lisa's face: she doesn't always appear to be smiling. There's question as to whether it was intentional, but new research ...
The color indicates the temperature the steel reached, which made this one of the earliest practical uses of thin-film interference. Iridescent interference colors in an oil film. Iridescence caused by thin-film interference is a commonly observed phenomenon in nature, being found in a variety of plants and animals.
