Protective eyewear is beneficial to those who are working with or those who might be exposed to ultraviolet radiation, particularly short wave UV.
Ultraviolet lamps are used to sterilize workspaces and tools used in biology laboratories and medical facilities.
Many birds have patterns in their plumage that are invisible at usual wavelengths but observable in ultraviolet, and the urine of some animals is much easier to spot with ultraviolet.
Ultraviolet detectors generally use either a solid-state device, such as one based on silicon carbide or aluminum nitride, or a gas-filled tube as the sensing element.
The terms chemical rays and heat rays were eventually dropped in favor of ultraviolet and infrared radiation, respectively.
Ultraviolet radiation may be subdivided into three regions: near UV (NUV; wavelength range of 380–200 nanometers), far or vacuum UV (FUV or VUV; 200–10 nm), and extreme UV (EUV or XUV; 1–31 nm).
UV light can be used to pasteurize fruit juices by flowing the juice over a high intensity ultraviolet light source.
Ultraviolet radiation is used for very fine resolution photolithography, a procedure where a chemical known as a photoresist is exposed to UV radiation which has passed through a mask.
The Sun emits ultraviolet radiation in the UVA, UVB, and UVC bands, but because of absorption in the atmosphere's ozone layer, 99 percent of the ultraviolet radiation that reaches the Earth's surface is UVA.
Some animals, notably in aquatic environments, also take steps to camouflage the odors they create that may attract predators.
Ultraviolet radiation is used in several food processes to remove unwanted microorganisms.
Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays.
Ultraviolet lamps are also used in analyzing minerals, gems, and in other detective work including authentication of various collectibles.
Degradation of insulation of electrical apparatus or pollution causes corona, wherein a strong electric field ionizes the air and excites nitrogen molecules, causing the emission of ultraviolet radiation.
The technique involves taking pictures of the illegible papyruses using different filters in the infrared or ultraviolet range, finely tuned to capture certain wavelengths of light.
UVC rays are the highest energy, most dangerous type of ultraviolet light.
Ultraviolet fly traps are used for the elimination of various small flying insects.
Materials may look the same under visible light, but fluoresce to different degrees under ultraviolet light; or may fluoresce differently under short wave ultraviolet versus long wave ultraviolet.
Ultraviolet radiation has other medical applications, in the treatment of skin conditions such as psoriasis and vitiligo.
Many fruits, flowers, and seeds stand out more strongly from the background in ultraviolet wavelengths as compared to human color vision.
