Ultraviolet light is useful for many things from cool looking posters and party decorations to helping law enforcement find body fluids and evidence. Some government issued documents, like passports, have watermarks built in that can only bee seen under UV lights to check authenticity. Crime Scene Investigators can use UV lights to find blood that has been "cleaned" up, semen on surfaces, and other fluids that the suspect thought they wiped away. Many night clubs also use UV lights with invisible stamping to determine paying or underage customers. So the question maybe shouldn't be what can ultraviolet lights be used to find but rather what can they NOT find!
What else can I help you with?
An ultraviolet light could be used to search for?

Ultraviolet light could be used to search for?
willemite
What mineral could ultraviolet light be used to find?
Ultraviolet light can be used to find minerals such as scheelite, which fluoresces bright blue under UV light. This fluorescence is helpful in mineral identification and exploration.
Can ultraviolet light be used to identify willemite?
Yes, ultraviolet light can be used to identify willemite, a mineral that usually shows a green fluorescence under short-wave ultraviolet light. This fluorescence property is a key characteristic used in mineral identification.
What light is used in black lights?
Ultraviolet light.
What instruments are used to detect ultraviolet light?
Instruments commonly used to detect ultraviolet light include photomultiplier tubes, photodiodes, and ultraviolet-sensitive cameras. These instruments are designed to convert incoming ultraviolet light photons into measurable electrical signals for analysis.

Why is invisible light important?
Invisible light, such as ultraviolet and infrared light, is important for various reasons. Ultraviolet light helps in Vitamin D synthesis in the skin and can be used to kill germs. Infrared light is used in technology for communication, remote controls, and thermal imaging.
