Visible spectrum - Wikipedia, the free encyclopedia The visible spectrum (or sometimes optical spectrum) is the portion of the electromagnetic spectrum that is visible to the human eye. Helium was first detected through an analysis of the spectrum of the Sun; chemical elements can be detected in astronomical objects by emission lines and absorption lines; the shifting of spectral lines can be used to measure the redshift or blueshift of distant or fast-moving objects. There are no exact bounds to the visible spectrum; a typical human eye will respond to wavelengths from 400 to 700 nm, although some people may be able to perceive wavelengths from 380 to 780 nm. en.wikipedia.org /wiki/Optical_spectrum   (898 words)

Spectrum - Wikipedia, the free encyclopedia Sometimes, the word spectrum refers to the compound signal itself, such as the "spectrum of visible light", a reference to those electromagnetic waves which are visible to the human eye. Thus a spectrum is a usually 2-dimensional plot, of a compound signal, depicting the components by another measure. In the 17th century the word spectrum was introduced into optics, referring to the range of colors observed when white light was dispersed through a prism. en.wikipedia.org /wiki/Spectrum   (456 words)

ZX Spectrum - Wikipedia, the free encyclopedia Several peripherals for the Spectrum were marketed by Sinclair: the ZX Printer was already on the market, as the Spectrum had retained the protocol and expansion bus from the ZX81. The Spectrum had an interesting method of handling colour; the colour attributes were held in a 32×24 grid, separate from the text or graphical data, but was still limited to only two colours in any given character cell. The Spectrum's video display, although rudimentary by today's standards, was perfect at the time for display on portable TV sets, and did not present much of a barrier to game development. en.wikipedia.org /wiki/ZX_Spectrum   (3693 words)

Electromagnetic Spectrum Encyclopedia Article @ LocalColorArt.com A rainbow shows the optical (visible) part of the electromagnetic spectrum; infrared (if you could see it) would be located just beyond the red side of the rainbow with ultraviolet appearing just beyond the violet end. The electromagnetic spectrum, shown in the table, extends from frequencies used in the electric power grid (at the long-wavelength end) to gamma radiation (at the short-wavelength end), covering wavelengths from thousands of kilometres down to fractions of the size of an atom. If the spectrum is composed of background light, parts of which the object transmits and parts of which it absorbs, an absorption spectrum occurs. localcolorart.com /encyclopedia/Electromagnetic_spectrum   (1585 words)

The Electromagnetic Spectrum The electromagnetic spectrum is the distribution of electromagnetic radiation according to energy (or equivalently, by virtue of the relations in the previous section, according to frequency or wavelength). The visible part of the spectrum may be further subdivided according to color, with red at the long wavelength end and violet at the short wavelength end, as illustrated (schematically) in the following figure. A graphical representation of the electromagnetic spectrum is shown in the figure below. csep10.phys.utk.edu /astr162/lect/light/spectrum.html   (205 words)

FCC Strategic Goals: Spectrum NTIA manages spectrum used by the Federal government (e.g., air traffic control and national defense) and the FCC is responsible for spectrum used by others, including individuals (e.g., garage door openers and computer modems), private organizations (e.g., radio and television broadcasters), and public safety and health officials (e.g., police and emergency medical technicians). Because there is a finite amount of spectrum and a growing demand for it, effectively managing the available spectrum is a strategic issue for the FCC and the NTIA. Spectrum encompasses the entire range of electromagnetic radio frequencies used in the transmission of sound, data, and video. www.fcc.gov /spectrum   (296 words)

Stuart Minor Benjamin, the Logic Of Scarcity: Idle Spectrum As A First Amendment Violation, 52 Duke L. J. 1 (2003) More intensive use of spectrum that is already licensed but is underutilized or inefficiently utilized has the potential to help alleviate imbalances between the supply and demand for spectrum in certain markets, address the problem of underserved rural areas, and, in general, ensure the efficient provision of existing and new wireless services to all markets. In the former case, the spectrum is not usable by anyone, and in the latter it is usable only for certain services, which services might not occupy all of the available bandwidth. Thus the fact that spectrum is subject to interference provides no information about spectrum that might distinguish it from anything else or justify any regime different from the one applicable to all other goods. www.law.duke.edu /journals/dlj/articles/dlj52p1.htm   (18989 words)

Electromagnetic Spectrum - Introduction The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. This is because most of the radio part of the EM spectrum falls in the range from a about 1 cm to 1 km (30 gigahertz (GHz) to 100 kilohertz (kHz)). Electromagnetic radiation from space is unable to reach the surface of the Earth except at a very few wavelengths, such as the visible spectrum, radio frequencies, and some ultraviolet wavelengths. imagine.gsfc.nasa.gov /docs/science/know_l1/emspectrum.html   (1292 words)

The Electromagnetic and Visible Spectra When all the wavelengths of the visible light spectrum strike your eye at the same time, white is perceived. Each individual wavelength within the spectrum of visible light wavelengths is representative of a particular color. In this sense, we are referring to visible light, a small spectrum of the enormous range of frequencies of electromagnetic radiation. www.glenbrook.k12.il.us /gbssci/phys/Class/light/u12l2a.html   (670 words)

Planet Sinclair: Computers: ZX Spectrum The Spectrum continued to sell into the early 1990s, but by about 1992 it had been squeezed out by the more advanced 16-bit computers and the cheap but more capable Sega and Nintendo games consoles. A licensed clone of the ZX Spectrum, the TS 2068, was launched in the United States by Timex in late 1983 (see the As well as all of these different product versions, no less than thirteen different versions of the basic hardware appeared during the six years that the Spectrum was produced. www.nvg.ntnu.no /sinclair/computers/zxspectrum/zxspectrum.htm   (355 words)

Spectra The visual spectrum of light, however, is but a tiny portion of the whole picture, of a huge spectrum of radiation that extends in both directions from the edges of the rainbow. The rainbow is a natural spectrum caused by the refraction and reflection of sunlight through raindrops, and shows that sunlight consists of a continuous run - - a continuum -- of colors from red to violet. Together they constitute the "visual spectrum" (or "optical spectrum") because it is the part of the full spectrum that is seen with the human eye. www.astro.uiuc.edu /~kaler/sow/spectra.html   (5857 words)

Unscrupulous Marketing by Spectrum Energy, Bournemouth Spectrum seem to think that, because they first obtain, by phone, the potential customer's agreement that they may visit, that the contract is not covered by a right to cancel. He recalls that hidden cameras showed a Spectrum employee first putting great pressure-to-buy on a single lady, and then (and I quote) he "ended up rooting through her handbag when she left the room". If Spectrum Energy is effectively denying the right to cancel to people whom they approach with a clever sales pitch, then the law is failing people like my parents. home.btconnect.com /tg/spectrum.htm   (2450 words)
