See all on Wikipediahttps://en.wikipedia.org/wiki/UltravioletUltraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), 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 … See more
Ultraviolet rays are invisible to most humans. The lens of the human eye blocks most radiation in the wavelength range of 300–400 nm; shorter wavelengths are blocked by the cornea. Humans also lack color receptor adaptations … See more
Very hot objects emit UV radiation (see black-body radiation). The Sun emits ultraviolet radiation at all wavelengths, including the extreme ultraviolet where it crosses into X-rays … See more

Weliswaar zijn de lichtgevoelige cellen in het netvlies van het menselijk oog gevoelig voor deze straling, maar de ooglens laat het niet door en beschermt daardoor het netvlies. De ooglens zelf ontwikkelt na la…

Ces rayons UV sont classés dans trois catégories en fonction de leur longueur d'onde : les UV-A (400-315 nm), UV-B (315-280 nm) et UV-C (280-100 nm). Toutefois, en raison de l'absorption des UV par la couche d'ozone …
