Colour distribution of a Newton disk. The Newton disk, also known as the disappearing color disk, is a well-known physics experiment with a rotating disk with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo, and violet, commonly known by the abbreviation ROYGBIV) appearing as white (or off-white or grey) when it's spun rapidly about its axis.

This limited edition reissue was released in a cardboard gatefold sleeve (mini LP-style paper jacket), featuring the "high-fidelity" SHM-CD manufacturing process (compatible with standard CD players) and was part of a two-album Rainbow cardboard sleeve reissue series featuring Rainbow Rising and Down to Earth. Both feature the unique-to-Japan ...
The rainbow hologram (also known as Benton hologram) is a type of hologram that was invented in 1968 by Dr. Stephen A. Benton at Polaroid Corporation (later MIT). [1] Rainbow holograms are designed to be viewed under white light illumination, rather than laser light which was required before this.
Over most of the disc, scattered light at all wavelengths overlaps, resulting in white light which brightens the sky. At the edge, the wavelength dependence of the scattering gives rise to the rainbow. [5] The light of a primary rainbow arc is 96% polarised tangential to the arc. [6] The light of the second arc is 90% polarised.
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).
6/10 [5] Difficult to Cure is the fifth studio album by the British hard rock band Rainbow , and it was released in 1981. It was the first album to feature Bobby Rondinelli on drums and Joe Lynn Turner on lead vocals after the departures of Cozy Powell and Graham Bonnet respectively, following the release of Down to Earth .
Thus the radius of the spurious disk of a faint star, where light of less than half the intensity of the central light makes no impression on the eye, is determined by [s = 1.17/a], whereas the radius of the spurious disk of a bright star, where light of 1/10 the intensity of the central light is sensible, is determined by [s = 1.97/a].
