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.
The best-known floppy disk drive for the C64, the 1541 is a single-sided 170-kilobyte drive for 5¼" disks. The 1541 directly followed the Commodore 1540 (meant for the VIC-20). The disk drive uses group coded recording (GCR) and contains a MOS Technology 6502 microprocessor, doubling as a disk controller and on-board disk operating system ...
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.
An optical disc is a flat, usually [note 1] disc-shaped object that stores information in the form of physical variations on its surface that can be read with the aid of a beam of light. Optical discs can be reflective, where the light source and detector are on the same side of the disc, or transmissive, where light shines through the disc to ...
The Commodore 1540 (also known as the VIC-1540) is the companion floppy disk drive for the VIC-20 home computer.It was introduced in 1982. [3] [4] It uses single-sided 5¼" floppy disks, on which it stores roughly 170 kB of data utilizing Commodore's GCR data encoding scheme.
