The ABCs of UV Light
The Differences Between UV-A, UV-B, & UV-C
Ultraviolet (UV) light is a form of energy that occupies a small potion of the electromagnetic radiation spectrum, with a shorter wavelength than that of visible light and a longer wavelength than that of X-rays. Wavelengths in these regions are commonly measured in nanometers (nm), which are a billionth of a meter or a thousandth of a micron. UV ranges from about 200-400 nm and is separated into three regions, UV-A, UV-B, and UV-C. UV occurs naturally in sunlight but can also be found in many man-made systems.
