1 : Introduction
This guide is an introduction to ultraviolet light and a guide
to using black light, a form of ultraviolet light.
Ultraviolet (UV) light is a range of light invisible to human
eyes. While it cannot be seen, UV light is useful to humans in
a wide range of areas. Astronomers measure UV light to study
stars and planets. Medical doctors use UV light to identify and
treat ailments. Geologists use UV light to identify gems. Ephemera
collectors use UV to identify fake collectibles. Police detectives
use UV in criminal investigations. Civil engineers use UV to
purify water and air. Kids and kids at heart use UV to make cool
glow in the dark art. The list goes on and on.
As you'll see in this book, one of the keys to ultraviolet
light is that it makes some materials fluoresce or glow in the
dark. This florescence ranges in color and brightness, and helps
scientists and hobbyists identify and study material. This fluorescence
is also what also allows people to make glow in the dark arts
and crafts.
