Goethe argued that the continuous spectrum was a compound phenomenon. Goethe used the word spectrum ( Spektrum) to designate a ghostly optical afterimage, as did Schopenhauer in On Vision and Colors. In the 18th century, Johann Wolfgang von Goethe wrote about optical spectra in his Theory of Colours. Comparing Newton's observation of prismatic colors to a color image of the visible light spectrum shows that "indigo" corresponds to what is today called blue, whereas his "blue" corresponds to cyan. ![]() Evidence indicates that what Newton meant by "indigo" and "blue" does not correspond to the modern meanings of those color words. For this reason, some later commentators, including Isaac Asimov, have suggested that indigo should not be regarded as a color in its own right but merely as a shade of blue or violet. The human eye is relatively insensitive to indigo's frequencies, and some people who have otherwise-good vision cannot distinguish indigo from blue and violet. He later added indigo as the seventh color since he believed that seven was a perfect number as derived from the ancient Greek sophists, of there being a connection between the colors, the musical notes, the known objects in the Solar System, and the days of the week. Newton originally divided the spectrum into six named colors: red, orange, yellow, green, blue, and violet. Newton's observation of prismatic colors ( David Brewster 1855) 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 hypothesized light to be made up of "corpuscles" (particles) of different colors, with the different colors of light moving at different speeds in transparent matter, red light moving more quickly than violet in glass. 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. He was the first to use the word spectrum ( Latin for "appearance" or "apparition") in this sense in print in 1671 in describing his experiments in optics. In the 17th century, Isaac Newton discovered that prisms could disassemble and reassemble white light, and described the phenomenon in his book Opticks. In the 13th century, Roger Bacon theorized that rainbows were produced by a similar process to the passage of light through glass or crystal. This reflects the fact that non-spectral purple colors are observed when red and violet light are mixed. Newton's circle places red, at one end of the spectrum, next to violet, at the other. The circle completes a full octave, from D to D. The spectral colors from red to violet are divided by the notes of the musical scale, starting at D. Newton's color circle, from Opticks of 1704, showing the colors he associated with musical notes. The near infrared (NIR) window lies just out of the human vision, as well as the medium wavelength infrared (MWIR) window, and the long-wavelength or far-infrared (LWIR or FIR) window, although other animals may perceive them. The optical window is also referred to as the "visible window" because it overlaps the human visible response spectrum. An example of this phenomenon is when clean air scatters blue light more than red light, and so the midday sky appears blue (apart from the area around the sun which appears white because the light is not scattered as much). Visible wavelengths pass largely unattenuated through the Earth's atmosphere via the " optical window" region of the electromagnetic spectrum. Colors containing only one wavelength are also called pure colors or spectral colors. Unsaturated colors such as pink, or purple variations like magenta, for example, are absent because they can only be made from a mix of multiple wavelengths. The spectrum does not contain all the colors that the human visual system can distinguish. The optical spectrum is sometimes considered to be the same as the visible spectrum, but some authors define the term more broadly, to include the ultraviolet and infrared parts of the electromagnetic spectrum as well. Under optimal conditions these limits of human perception can extend to 310 nm ( ultraviolet) and 1100 nm ( near infrared). These boundaries are not sharply defined and may vary per individual. In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz. ![]() A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. ![]() |
