The wavelength range where optical radiation is visible does not have sharp borders. Here, the wavelength band of 380 nm to 780 nm is used. There is an overlap with the UV wavelength range that extends to 400 nm and in the upper range with Infrared.

1 de abr. de 2020 · The human eye sees color over 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.
Approximate wavelength For the various colors. 1 Angstrom = 10 -10 meters. The order of colors in light, arranged from shortest wavelength to longest, is called the visible spectrum of light. The image below shows light's visible spectrum, which runs from violet to red.
The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band.
For example, light with a wavelength of 470 nm is blue, light with a wavelength of 540 nm is green, and light with a wavelength of 650 nm is red. Visible light could be described as the kind of light that we humans are familiar with because of our ability to see it.
In telecommunications, visible light communication (VLC) is the use of visible light (light with a frequency of 400–800 THz/wavelength of 780–375 nm) as a transmission medium. VLC is a subset of optical wireless communications technologies.
