    May 2, 2024 · The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10 -7 m, which is red).

    Under optimal conditions, these limits of human perception can extend to 310 nm (ultraviolet) and 1100 nm (near infrared). [5] [6] [7] The spectrum does not contain all the colors that the human visual system can distinguish.

    Jun 7, 2024 · The human eye sees color wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light or the visible spectrum, because humans can see it.

    Isaac Newton coined the word spectrum in 1671 in his book Opticks. Spectrum is Latin for “appearance” or “apparition” and Newton used the term to describe the rainbow spectrum produced by sunlight passing through a prism. Sunlight is a form of white light, which is the color you get when all of the wavelengths of light blend together. Newton saw th...

    Although scientists assign wavelength ranges for the colors, they are continuous. There aren’t any boundaries between one color and another. The wavelength limits of human vision are ambiguous, too. Some people can see further into the infrared and ultraviolet than others. Usually, humans (and animals) that can see further into one end of the spect...

    The eyes and brain see many more colors than those of the visible light spectrum. For example, purple and magenta aren’t on the spectrum. They are the brain’s way of connecting red and purple. There are also desaturated and blended colors, such as pink and brown. Mixing pigments on a palette forms hues and tints that aren’t spectral colors.

    Visible light - that which is detectable by the human eye - consists of wavelengths ranging from approximately 780 nanometer (7.80 x 10 -7 m) down to 390 nanometer (3.90 x 10 -7 m). Specific wavelengths within the spectrum correspond to a specific color based upon how humans typically perceive light of that wavelength.
