The term polychromatic means having several colors. It is used to describe light that exhibits more than one color , which also means that it contains radiation of more than one wavelength . The study of polychromatics is particularly useful in the production of diffraction gratings .
In the third part, chapters 11–22, polychromatic patterns (3 or more colors), polychromatic line groups, and polychromatic plane groups are derived and illustrated. Loeb's synthetic approach does not enable a comparison of colour symmetry concepts and definitions by other authors, and it is therefore not surprising that the number of ...
Polychrome brickwork also became popular in Europe in the later 19th century as part of the various medieval and Romanesque revivals. In France, the Menier Chocolate Factory in Noisiel, designed by Jules Saulnier and completed in 1872, is an early and very elaborate example, which is also noted for its early use of iron structure.
Polychromatic symmetry is a colour symmetry which interchanges three or more colours in a symmetrical pattern. It is a natural extension of dichromatic symmetry . The coloured symmetry groups are derived by adding to the position coordinates ( x and y in two dimensions, x , y and z in three dimensions) an extra coordinate, k , which takes three ...
Polychromatic red blood cells appear bluish-gray on the blood smear. Polychromasia is a disorder where there is an abnormally high number of immature red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow during blood formation ( poly - refers to many , and -chromasia means color .)
Metallic paint, which may also be called metal flake (or incorrectly named polychromatic), is a type of paint that is most common on new automobiles, but is also used for other purposes. Metallic paint can reveal the contours of bodywork more than non-metallic, or "solid" paint.
The four pigments in a bird's cone cells (in this example, estrildid finches) extend the range of color vision into the ultraviolet. [1]Tetrachromacy (from Greek tetra, meaning "four" and chroma, meaning "color") is the condition of possessing four independent channels for conveying color information, or possessing four types of cone cell in the eye.
Segmented turning, also known as polychromatic turning, is a form of woodturning on a lathe where the initial workpiece is composed of multiple parts glued together. The process involves gluing several pieces of wood to create patterns and visual effects in turned projects.
