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 White Book refers to a standard of compact disc that stores pictures and video. CD-i Bridge [ 18 ] - a bridge format between CD-ROM XA and the Green Book CD-i , which is the base format for Video CDs , Super Video CDs and Photo CDs .
On 12 April 2012 a picture disc album version of Long Live Rock 'n' Roll was released in the US as part of Record Store Day 2012. A deluxe edition version was released on 13 November in Europe, featuring rough mixes of the album tracks from July 1977 except "Gates of Babylon", which was written later.
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].
The images are simulations of the Arago spot in the shadow of discs of diameter 4 mm, 2 mm, and 1 mm, imaged 1 m behind each disc. The disks are illuminated by light of wavelength of 633 nm, diverging from a point 1 m in front of each disc. Each image is 16 mm wide.
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).
