What Are the Uses of Ultraviolet Light? | Sciencing

Apr 26, 2018 · By Claire Gillespie. Ultraviolet light, commonly known as UV light, is one type of electromagnetic radiation that comes from the sun and is transmitted at different wavelengths and frequencies. On the electromagnetic spectrum, UV light falls between visible light and X-rays and can be split into UVA or near UV, UVB or middle UV, and UVC or far UV. Ultraviolet light has many …

Ultraviolet - Wikipedia

Ultraviolet (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 radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiat…

Ultraviolet (UV) Radiation | UCAR Center for Science Education

Ultraviolet radiation lies between visible light and X-rays along the electromagnetic spectrum. UV "light" spans a range of wavelengths between about 10 and 400 nanometers. The wavelength of violet light is around 400 nanometers (or 4,000 Å). Ultraviolet radiation oscillates at rates between about 800 terahertz (THz or 10 12 hertz) and 30,000 THz.

Ultraviolet - Wikipedia

A black light lamp emits long-wave UVA radiation and little visible light. Fluorescent black light lamps work similarly to other fluorescent lamps, but use a phosphor on the inner tube surface which emits UVA radiation instead of visible light. Some lamps use a deep-bluish-purple Wood's glassoptical filter that blocks almost all visible light with wavelengths longer than 400 nanometers. Others use plain glass instead of the more expensive Wood's glass, so they appear light-blue to the eye when operating. Inca…
