are visible light slower or faster than ultraviolet
Ultraviolet Light Ultraviolet (UV) light is light with higher frequency (lower wavelength) than visible light. UV light has frequencies ranging from 8*10 14 to 3*10 16 Hz (800 THz to 30 PHz) and wavelengths from 10 -8 m to 3.8*10 -7 m (10 nm to 380 nm).
