OK, it’s not really a black light. It’s better to call it what it is: ultraviolet light. Let’s start with a quick overview of light. Of course, light is an electromagnetic wave (oscillating electric and magnetic fields), but in this case the frequency is the important aspect. For some narrow range of frequencies, the human eye can detect these waves—this is called the visible spectrum. The lower frequency waves are interpreted by our eyes as the color red, and the higher frequency would be violet.
