UV light is classified as which type of radiation?

Ultraviolet (UV) light is classified as invisible radiation because it lies outside the visible spectrum of light that the human eye can perceive. While visible radiation includes wavelengths from approximately 400 to 700 nanometers, UV light ranges from about 10 to 400 nanometers, making it beyond the detection capability of human vision. This characteristic is essential in various applications, such as sterilization and disinfection processes in water treatment systems, where UV radiation can effectively inactivate microorganisms without being visible. Understanding the properties of UV light and its classification is crucial in contexts where its germicidal effects are utilized, reinforcing its role as an effective method for ensuring water safety in healthcare and other settings.
