Ultraviolet (UV) light is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.
In fisica la radiazione ultravioletta è un intervallo della radiazione elettromagnetica, appartenente allo spettro elettromagnetico, con lunghezza d'onda immediatamente inferiore alla luce visibile dall'occhio umano e immediatamente superiore a quella dei raggi X. Il termine significa "oltre il violetto", poiché il violetto è il ...
9 mar 2016 · The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm). Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth's surface.
