- The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.

Jul 27, 2015 · The lens normally blocks ultraviolet light, so without it, people are able to see beyond the visible spectrum and perceive wavelengths up to about 300 nanometres as having a blue-white...
A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. [3] In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz. These boundaries are not sharply defined and may vary per individual. [4]

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.

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.

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.
