Ultraviolet Light
Uses
UV is also used to detect counterfeit money, and to harden some types of dental filling.
At places that use UV lights, or "blacklights," as called by some, the lights illuminate clothes, making the clothes seem to glow. This is caused by certain chemicals in washing materials which fluoresce when hit by UV. The clothes absorb the light and re-radiate it at a longer wavelength.
For people with a Vitamin D deficiency, doctors usually prescribe small doses of UV light.
This is because the body produces Vitamin D when exposed to suitable amounts of UV.
More Information
Frequency: 7.5 x 10 to the 14th power - 3 x 10 to the 16th power.
Video
This video explains how UV light, when mixed among other materials, may "fluoresce," simply because of the photons it emits. Everything else did the same thing, not fully explaining UV, just the fluorescent part.

Gigi in Action
At the location of the link, you will find the main article on Gigi. It basically explains the
Anyway, Gigi takes a powerful UV light and amplifies that power even more. This is explained by the co-founder Mark Stibich. Specific material information is not given, as well as facts about when and where Gigi was made.
It does, however, explain the impact Gigi will have on this world. Seeing as she can wipe out all known diseases so far, soon hospitals will be as clean as ever, without a single germ to be seen (as technology advances, of course). Now, if a human were to stand in the room (And I'm sure you all know, this is meant only to clear up any misconceptions), they would die almost instantly.
