Ultraviolet radiation is invisible, but a small fraction of visible light passes through the filtering material, with wavelengths no longer than 400-410 nm, and as a result, when operating the lamp emits a dim purple or violet glow.

** Ultraviolet ( UV ) radiation is ionizing but it is not penetrating, so it can be shielded by thin opaque layers such as sunscreen, clothing, and protective eyewear.

STS-34 Atlantis ( October 18 to October 23, 1989 ) was a 5-day mission during which the deployed the Galileo spacecraft, on its journey to explore Jupiter, operated the Shuttle Solar Backscatter Ultraviolet Instrument ( SSBUV ) to map atmospheric ozone and performed numerous secondary experiments involving radiation measurements, polymer morphology, lightning research, microgravity effects on plants and a student experiment on ice crystal growth in space.

It also causes sunburn, and has other medical effects such as the production of vitamin D. Ultraviolet light is strongly attenuated by Earth's ozone layer, so that the amount of UV varies greatly with latitude and has been partially responsible for many biological adaptations, including variations in human skin color in different regions of the globe.

In the case of Ultraviolet Photoelectron Spectroscopy ( UPS ), the surface of a solid sample is irradiated with ultraviolet ( UV ) light and the kinetic energy of the emitted electrons is analysed.

* Ultraviolet B lighting is required for indoor turtles.

Ultraviolet light emitted by the sample is detected for measurement.

Ultraviolet light ( UV ) is very effective at inactivating cysts, in low turbidity water.

The Ultraviolet catastrophe is the error at short wavelengths in the Rayleigh – Jeans law ( depicted as " classical theory " in the graph ) for the energy emitted by an ideal black-body.

Ultraviolet lights have many uses, but black lights are essential when UV light without visible light is needed, particularly in observing fluorescence, the colored glow that many substances emit when exposed to UV.

Ultraviolet light is also used at aquatic facilities.

* Ultraviolet light irradiation ( UV, from a germicidal lamp ) is useful only for sterilization of surfaces and some transparent objects.

The College is home to four recognized Colorado State University Programs of Research and Scholarly Excellence: the Department of Atmospheric Science, the Center for Extreme Ultraviolet Science and Technology, the Engines and Energy Conversion Laboratory, and the Environmental and Water Resources Engineering Program.

Ultraviolet ( UV-A ) radiation of adequate intensity ( 1, 000 micro-watts per centimeter squared is common ), along with low ambient light levels ( less than 2 foot-candles ) for fluorescent penetrant examinations.

Ultraviolet ( UV ) light curing adhesives, also known as light curing materials ( LCM ), have become popular within the manufacturing sector due to their rapid curing time and strong bond strength.

In Ultraviolet these methods allow the vampire hunters to develop modern weaponry to fend off their foes-instead of stakes, they carry automatic handguns and submachine guns with carbon bullets and specialized sights that use video cameras to differentiate between vampires and humans ( vampires are invisible to recording devices ); instead of wreaths of garlic, gas grenades containing concentrated allicin ; instead of sunlight, lamps emitting ultraviolet light.
