Ultraviolet light is high energy light lying beyond the spectrum visible to the human eye. Many elements and chemicals can absorb ultraviolet light and re-emit it in the visible region. These processes are called fluorescence and phosphorescence.

The emitters absorb the UV light based on empty energy levels in their make-up and vibrate, rotate or otherwise use some the energy before re-emitting it at a lower energy falling in the visible spectrum. Ultraviolet light as described by its wavelength with UV-A having the longest wavelength. UV-A is commonly known as "black light", popularly used for illuminating posters and other novelties. UV-A is not normally dangerous in the way UV-B and C from the sun are in regards to cancer or eye damage.To find this cache you will need a UV-A source.

A small handheld black light tube will work as would a UV LED flashlight or really any other source advertised as a black light.
