Scientists divide the UV spectrum into three classes: UV-A, UV-B and UV-C. UV-A radiation is closest to the visible spectrum and has the lowest energy while UV-C is farthest from visible light and ...

Some people can see much more of the UV light spectrum, however. Up until the 1980s , cataract surgery involved removing the cloudy lens from the eye and not implanting a replacement, so people ...

The ultraviolet index measures the intensity of the sun's harmful rays. Learning how to read it can help you protect your ...

A particular spectrum of ultraviolet light, far UV-C, “efficiently inactivates bacteria without harm to exposed mammalian skin,” according to a study published in Nature.

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can ...

UV-Vis spectroscopy analysis, absorption spectrum and absorbance units. UV-Vis spectroscopy information may be presented as a graph of absorbance, optical density or transmittance as a function of ...

Safety Month – but how much do we really know about UV light and the effects it has on our bodies? UV rays are difficult to ...
