What is the wavelength range of UV?
The wavelength range of UV is 300 to 380 nanometers (nm). UV light is invisible to the human eye. Long-term UV exposure can result in fading and deterioration of fabrics and furnishings. Infrared light is also invisible to the human eye. It falls between approx. 790-3000 nm and has a penetrating heat effect. The only portion of the solar spectrum that is visible to the human eye is the visible light range, 380-720 nm.
