What is Newton's colour disc ? What are primary colours? EXPLAIN
Answers
Explanation:
''Newton disc''' also known as Disappearing Colour Disc is a well-known physics experiment with a rotating disc with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo and violet) appearing as white (or off-white or gray) when it spins very fast. type of mix of light stimuli is called temporal optical mixing, a version of additive-averaging mixing.[1] The concept that human visual perception cannot distinguish details of high-speed movements is popularly known as persistence of vision.
The disc is named after Isaac Newton. Although he published a circular diagram with segments for the primary colors that he had discovered, it is uncertain whether he actually ever used a spinning disc to demonstrate the principles of light.
Transparent variations for magic lantern projection have been produced.[2]
A Newton disc is a disc with segments in rainbow colours. When the disc is rotated, the colors fade to white; In this way Isaac Newton demonstrated that white light is a combination of the seven different colours found in a rainbow. A Newton Disc can be created by painting a disc with the seven different colours.
A set of primary colors is a set of colorants or colored lights that can be combined in varying amounts to produce a gamut of colors. This is the essential method used in applications that are intended to elicit the perception of diverse sets of color, e.g. electronic displays, color printing, and paintings.
