Black lights generate ultraviolet light by passing electricity through a tube containing mercury vapor and inert gas, causing the mercury atoms to emit energy. This ultraviolet light is invisible to the human eye, but phosphor coatings on the tube's outer surface fluoresce different colors when exposed to the UV light. Common uses of black lights include examining tattoos, currency, and other items for hidden details, as well as for entertainment purposes at parties, night clubs, and theme parks.
