Ultraviolet \Ul`tra*vi"o*let\, a. [Pref. ultra- + violet.] (Physics) Lying outside the visible spectrum at its blue-violet end; -- said of light more refrangible (i. e. having a shorter wavelength) than the extreme violet rays of the visible spectrum. Electromagnetic radiation with wavelengths shorter than those of ultrviolet light are not usually considered as light waves, but are classified differently. The ultraviolet region of the electromagnetic spectrum is generally considered as comprising those electromagnetic emissions with wavelengths lying between those of visible light and those of X-rays, i. e. between 4000 Angstroms and 100 Angstroms.

Ultraviolet is a 1998 United Kingdom television series written and directed by Joe Ahearne and starring Jack Davenport, Susannah Harker, Idris Elba and Philip Quast. The music was composed and performed by Sue Hewitt. The programme was produced by World Productions for Channel 4.
Ultraviolet refers to electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays.
Ultraviolet or UltraViolet may also refer to:
UltraViolet is a women's advocacy group based in the United States. The group conducts online campaigns using social media to highlight women's issues such as violence against women, maternity leave, equal pay, and reproductive rights.
Ultraviolet (UV) is an electromagnetic radiation with a wavelength from 10 nm (30 PHz) to 380 nm (750 THz), shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight. It is also produced by electric arcs and specialized lights such as mercury-vapor lamps, tanning lamps, and black lights. Although lacking the energy to ionize atoms, long-wavelength ultraviolet radiation can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.
Suntan, freckling and sunburn are familiar effects of over-exposure, along with higher risk of skin cancer. Living things on dry land would be severely damaged by ultraviolet radiation from the Sun if most of it were not filtered out by the Earth's atmosphere. More-energetic, shorter-wavelength "extreme" UV below 121 nm ionizes air so strongly that it is absorbed before it reaches the ground. Ultraviolet is also responsible for the formation of bone-strengthening vitamin D in most land vertebrates, including humans. The UV spectrum thus has effects both beneficial and harmful to human health.
Near-UV light is visible to some insects, mammals, and birds. Small birds have a fourth color receptor for ultraviolet light; this gives birds "true" UV vision. Reindeer use near-UV light to see polar bears, who are poorly visible in regular light because they blend in with the snow. UV light also allows mammals to see urine trails, which is helpful for prey animals to find food in the wild. The males and females of some butterfly species look identical to the human eye but very different to UV-sensitive eyes—the males sport bright patterns in order to attract the females Most ultraviolet rays are invisible to most humans: the lens on a human eye ordinarily filters out UVB frequencies or lower, and humans lack color receptor adaptations for ultraviolet light, so humans don’t see many of the "light or colours" certain animals see.
Under some conditions, children and young adults can see ultraviolet down to wavelengths of about 310 nm, and people with aphakia (missing lens) or replacement lens can also see some UV wavelengths. People who don't have lenses often report seeing ultraviolet light that looks "whitish blue" or "whitish violet". This happens because our three color receptors ( red, green and blue) are all sensitive to ultraviolet light, so the light comes in as a mixture of the three receptors, with a slight nod to blue side of the spectrum.
Ultraviolet is a 2006 American dystopian science fiction action thriller film written and directed by Kurt Wimmer and produced by Screen Gems. It stars Milla Jovovich as Violet Song, Cameron Bright as Six, and Nick Chinlund as Ferdinand Daxus. It was released in North America on March 3, 2006. The film was released on DVD and Blu-ray Disc on June 27, 2006.
The film follows Violet Song Jat Shariff (Jovovich), a woman infected with hemoglophagia, a fictional vampire-like disease, in a future dystopia where anyone infected with the contagious disease is immediately sentenced to death. With her advanced martial arts, a group of rebel hemophages, and a boy named Six (Bright), whose blood may contain a cure for the disease, Violet goes on a mission to overthrow the futuristic government and defeat Ferdinand Daxus (Chinlund).
A novelization of the film was written by Yvonne Navarro, with more back-story and character development. The book differs from the film in a number of ways, including a more ambiguous ending and the removal of some of the more improbable plot twists. An anime series titled Ultraviolet: Code 044 was released by the Japanese anime satellite television network Animax, and created by Madhouse. Because of its many similarities with Equilibrium and because they share the same director, the film is often considered to be Equilibrium's spiritual successor.
Ultraviolet is a novelization of the science fiction film of the same name. It was adapted by Yvonne Navarro from the screenplay written by Kurt Wimmer. The novelization provides more backstory that the film was not able to accomplish. The novel is also based on the original screenplay by Kurt Wimmer before Sony heavily edited it.

"Ultraviolet (Light My Way)" is a song by the rock band U2 and the tenth track from their 1991 album Achtung Baby. Ostensibly about love and dependency, the song also lends itself to religious interpretations, with listeners finding allusions to the Book of Job and writers finding spiritual meaning in its invocation of the light spectrum.
The song's composition and recording incorporate both serious and throwaway elements, in keeping with the rest of Achtung Baby. While not released as a single, the song has appeared in two films and a U2 business venture was named after it. "Ultraviolet" played a featured role during the encores of the group's 1992–1993 Zoo TV and 2009–2011 U2 360° Tours.
Ultraviolet is the fourth and final studio album by All About Eve. It was the only album that the band released with MCA.
