Humans see light at the lower end of the visible spectrum, having a longer wavelength, about 740 nm, as red; we perceive light in the middle of the spectrum as green; and see light at the upper end of the spectrum, with a wavelength of about 380 nm, as violet. All other colors ...
electromagnetic spectrum The electromagnetic spectrum can be measured in frequencies or in wavelengths. This diagram measures wavelengths in meters, ranging from the longest wavelengths (radio waves) to the shortest (gamma rays). Visible light, which is a band of colors from red to violet, is the...

The colors of the visible spectrum are red, orange, yellow, green, blue, indigo, and violet. They are ordered from longest wavelength to shortest. They can be remembered with the acronym ROYGBIV. What is meant by visible spectrum? Visible light is the portion of the electromagnetic spectrum ...
light-adapted eye generally has its maximum sensitivity at around 555 nm (540 THz), in the green region of the optical spectrum (see: luminosity function). The spectrum does not, however, contain all the colors that the human eyes and brain can distinguish. Unsaturated colors such as pink,...
Light is not the only type of electromagnetic radiation—it is, in fact, only a small segment of the total electromagnetic spectrum—but it is the one form the eye can perceive. Wavelengths of light range from about 400 nm at thevioletend of thespectrumto 700 nm at theredend (seetable)...
Spectral Composition of Visible Light and Perceived Colors:White light consists of seven distinct waves of different frequencies, each of which appears as a different color in the visible spectrum. The perceived color by the human eye depends on ...
Rather, white is the combination of all the colors of the visible light spectrum. If all the wavelengths of the visible light spectrum give the appearance of white, then none of the wavelengths would lead to the appearance of black. Once more, black is not actually a color. Technically ...

1 It is also known as the optical spectrum of light or the spectrum of white light. Wavelength and Color Spectrum Chart The wavelength of light, which is related to frequency and energy, determines the color perceived by the human eye. The ranges of these different colors are listed in ...
