UV TypeWavelength Range (nanometers) UV-A315–400 nm UV-B280–315 nm UV-C100–280 nm Its Benefits and Limitations Germicidal ultraviolet disinfection is rapid, low-maintenance, and does not use chemicals or produce byproducts. To achieve proper disinfection of water, air, or surfaces, each med...
In the ERS, UV photons belong to a wavelength range between 10 and 400 nm (1 nm=10−9 m) and therefore possess wavelengths shorter than visible light (400–800 nm) but longer than X-rays (<10 nm). Photon energy and wavelength are also related by eqn [1], but the relationship can...
Ultraviolet (UV) radiation is a kind of non-lighting radiation with the wavelength range from 100nm to 400nm. Ultraviolet irradiance meters are now widely used in many areas. However, as the development of science and technology, especially in the field of light-curing industry, there are ...
Almost all of a UV lamp's output is concentrated in the 254 nanometers (nm) region in order to take full advantage of the germicidal properties of this wavelength. Most ultraviolet purification systems are combined with various forms of filtration, as UV light is only capable of killing ...

Ultraviolet (UV) light is electromagnetic radiation with a wavelength that is shorter than visible light and longer than x-rays, emitted at 100 to 400 nanometers (nm). The UV spectrum is divided into: UVA 315 to 400 nm UVB 280 to 315 nm ...
Bethe’s theory predicts that scattering by a small hole on a thin perfect electric conductor (PEC) is presented as radiation by an in-plane magnetic dipole of the incident magnetic field direction. Even in the near-infrared range where metals are no mor
While Hubble currently observes the Universe primarily at visible and ultraviolet wavelengths its scientific successor — the James Webb Space Telescope — will be sensitive to a range of wavelengths from 0.6 micrometers (orange light) to 28 micrometers, deep infrared radiation emitted from objects...
Radiation: Energy transmitted in the form of subatomic particles or waves. Radio waves: Longest form of electromagnetic radiation, measuring up to 6 miles (9.7 kilometers) from peak to peak. Ultraviolet radiation: Electromagnetic radiation of a wavelength just shorter than the violet (shortest wa...
