S s - abbreviation Technical meaning of SPECTRUM ZX Spectrum 3
- noun plural spectrum Physics. an array of entities, as light waves or particles, ordered in accordance with the magnitudes of a common physical property, as wavelength or mass: often the band of colors produced when sunlight is passed through a prism, comprising red, orange, yellow, green, blue, indigo, and violet. this band or series of colors together with extensions at the ends that are not visible to the eye, but that can be studied by means of photography, heat effects, etc., and that are produced by the dispersion of radiant energy other than ordinary light rays. Compare band spectrum, electromagnetic spectrum, mass spectrum. 1
- noun plural spectrum a broad range of varied but related ideas or objects, the individual features of which tend to overlap so as to form a continuous series or sequence: the spectrum of political beliefs. 1
- noun Definition of spectrum in Technology (computer) Sinclair's first personal computer with a colour display. The Spectrum used the Zilog Z80 processor like its predecessors the ZX-80 and ZX-81. It was originally available in 16k and 48k versions using cassette tape and later grew to 128k and sprouted floppy disks. It had a wider and more solid case and a marginally better "dead flesh" keyboard. Unlike the earlier models, it didn't require the presence of a cold carton of milk to prevent it overheating. It was possibly the most popular home computer in the UK for many years. The TK-90X was a clone. 1
- singular noun spectrum The spectrum is the range of different colours which is produced when light passes through a glass prism or through a drop of water. A rainbow shows the colours in the spectrum. 0
- countable noun spectrum A spectrum is a range of a particular type of thing. 0
- countable noun spectrum A spectrum is a range of light waves or radio waves within particular frequencies. 0
- noun spectrum the distribution of colours produced when white light is dispersed by a prism or diffraction grating. There is a continuous change in wavelength from red, the longest wavelength, to violet, the shortest. Seven colours are usually distinguished: violet, indigo, blue, green, yellow, orange, and red 0

- noun spectrum the series of colored bands dispersed and arranged in the order of their respective wavelengths by the passage of white light through a prism or other dispersing device and shading continuously from red (produced by the longest wave visible) through violet (produced by the shortest): the six main colors of the spectrum are red, orange, yellow, green, blue, and violet, with a seventh color (indigo) sometimes specified, between blue and violet 0
