FAQs about UV light for disinfection

December 6, 2020

Scientist Johann Wilhelm Ritter first discovered ultraviolet light in 1801. He determined that it was invisible electromagnetic radiation at wavelengths between 10-400 nm. In addition to UVA and UVB, which come to us from the sun, a third type, UVC, has the potential to disinfect spaces. Here are the most frequently asked questions.
