16 gen 2021 · Colors Beyond the Spectrum. 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.
Colors that can be produced by visible light of a narrow band of wavelengths (monochromatic light) are called pure spectral colors. The various color ranges indicated in the illustration are an approximation: The spectrum is continuous, with no clear boundaries between one color and the next.
In almost all depictions of the electromagnetic spectrum, visible light is shown as a rainbow, and adjacent parts of the spectrum are monotone in color - there is no UV or infrared rainbow to be seen.
27 lug 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 colour....
15 gen 2016 · The visible spectrum intentionally overlaps the UV-A (from ~360–380 to 400 nm in the deep violet) and well into the near-infrared (IR-A) spectral band, which begins at 780 nm.

To see the cosmos in light beyond the visible part of the spectrum, special instruments are needed, with different types of detectors depending on the wavelength. These instruments/detectors, allow astronomers to obtain a huge amount of information about the Universe. Galaxy observed at different wavelengths.
1 apr 2020 · Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it. Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.
