The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 3. Unsaturated colors such as pink, or purple variations such as magenta, are absent, for example, because they can be made only by a mix of multiple wavelengths. Colors containing only one wavelength are also called pure colors or spectral colors. Visible wavelengths pass through the . An example of this phenomenon is that clean air scatters blue light more than red wavelengths, and so the midday sky appears blue. The optical window is also referred to as the . The near infrared (NIR) window lies just out of the human vision, as well as the Medium Wavelength IR (MWIR) window, and the Long Wavelength or Far Infrared (LWIR or FIR) window, although other animals may experience them. History. Newton's color circle, from Opticks of 1. The spectral colors from red to violet are divided by the notes of the musical scale, starting at D. The circle completes a full octave, from D to D. Newton's circle places red, at one end of the spectrum, next to violet, at the other. This reflects the fact that non- spectral purple colors are observed when red and violet light are mixed. In the 1. 3th century, Roger Bacon theorized that rainbows were produced by a similar process to the passage of light through glass or crystal. He was the first to use the word spectrum (Latin for . Newton observed that, when a narrow beam of sunlight strikes the face of a glass prism at an angle, some is reflected and some of the beam passes into and through the glass, emerging as different- colored bands. Newton hypothesized light to be made up of . The result is that red light is bent (refracted) less sharply than violet as it passes through the prism, creating a spectrum of colors. Newton divided the spectrum into seven named colors: red, orange, yellow, green, blue, indigo, and violet. He chose seven colors out of a belief, derived from the ancient Greeksophists, of there being a connection between the colors, the musical notes, the known objects in the solar system, and the days of the week. For this reason, some later commentators, including Isaac Asimov. However, the evidence indicates that what Newton meant by . Comparing Newton's observation of prismatic colors to a color image of the visible light spectrum shows that . Goethe used the word spectrum (Spektrum) to designate a ghostly optical afterimage, as did Schopenhauer in On Vision and Colors. Goethe argued that the continuous spectrum was a compound phenomenon. Where Newton narrowed the beam of light to isolate the phenomenon, Goethe observed that a wider aperture produces not a spectrum but rather reddish- yellow and blue- cyan edges with white between them. The spectrum appears only when these edges are close enough to overlap. In the early 1. 9th century, the concept of the visible spectrum became more definite, as light outside the visible range was discovered and characterized by William Herschel (infrared) and Johann Wilhelm Ritter (ultraviolet), Thomas Young, Thomas Johann Seebeck, and others. Their theory of color vision correctly proposed that the eye uses three distinct receptors to perceive color. Animal color vision. Many species can see light within frequencies outside the human . Bees and many other insects can detect ultraviolet light, which helps them find nectar in flowers. Plant species that depend on insect pollination may owe reproductive success to their appearance in ultraviolet light rather than how colorful they appear to humans. Birds, too, can see into the ultraviolet (3. Bees' visible spectrum ends at about 5. The various color ranges indicated in the illustration are an approximation: The spectrum is continuous, with no clear boundaries between one color and the next. Spectroscopy is an important investigative tool in astronomy, where scientists use it to analyze the properties of distant objects. Typically, astronomical spectroscopy uses high- dispersion diffraction gratings to observe spectra at very high spectral resolutions. Helium was first detected by 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 Doppler shift (red shift or blue shift) of distant objects. Color display spectrum. Approximation of spectral colors on a display results in somewhat distorted chromaticity. A rendering of the visible spectrum on a gray background produces non- spectral mixtures of pure spectrum with gray, which fit into the s. RGB color space. Color displays (e. Colors outside the color gamut of the device, such as most spectral colors, can only be approximated. For color- accurate reproduction, a spectrum can be projected onto a uniform gray field. The resulting mixed colors can have all their R,G,B coordinates non- negative, and so can be reproduced without distortion. This accurately simulates looking at a spectrum on a gray background.
