2. Ultraviolet photography - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet_photography

   Ultraviolet photography is a photographic process of recording images by using radiation from the ultraviolet (UV) spectrum only. Images taken with ultraviolet radiation serve a number of scientific, medical or artistic purposes. Images may reveal deterioration of art works or structures not apparent under light. Diagnostic medical images may ...

3. Pierre Auger Observatory - Wikipedia

   en.wikipedia.org/wiki/Pierre_Auger_Observatory

   The Pierre Auger Observatory is an international cosmic ray observatory in Argentina designed to detect ultra-high-energy cosmic rays: sub-atomic particles traveling nearly at the speed of light and each with energies beyond 10 18 eV. In Earth's atmosphere such particles interact with air nuclei and produce various other particles.

4. Ultraviolet - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet

   Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, 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.

5. Sunlight - Wikipedia

   Extreme UV and X-rays are produced (left of wavelength range) but comprise very small amounts of the Sun's total output power (area under the curve). Although the solar corona is a source of extreme ultraviolet and X-ray radiation, these rays make up only a very small amount of the power output of the Sun (see spectrum at right).

   UltraViolet logo. UltraViolet was a cloud-based digital rights locker for films and television programs that allowed consumers to store proofs-of-purchase of licensed content in an account to enable playback on different devices using multiple applications from several different streaming services.

7. Ultraviolet astronomy - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet_astronomy

   Ultraviolet astronomy is the observation of electromagnetic radiation at ultraviolet wavelengths between approximately 10 and 320 nanometres; shorter wavelengths—higher energy photons—are studied by X-ray astronomy and gamma-ray astronomy. [1] Ultraviolet light is not visible to the human eye. [2]

8. Full-spectrum photography - Wikipedia

   en.wikipedia.org/wiki/Full-spectrum_photography

   Full-spectrum photography is a subset of multispectral imaging, defined among photography enthusiasts as imaging with consumer cameras the full, broad spectrum of a film or camera sensor bandwidth. In practice, specialized broadband/full-spectrum film captures visible and near infrared light, commonly referred to as the "VNIR". [1]

9. Ultraviolet (film) - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet_(film)

   The film was released on DVD and Blu-ray on June 27, 2006, in North America. [12] There are two versions of the film, an unrated version (94 minutes long) and a PG-13 version (88 minutes long). Additionally, the rough cut of the movie was originally close to two hours long; only six minutes of this lost half-hour were restored for the unrated cut.
