## Chemistry: The Central Science (13th Edition)

If you don't remember the wavelength range of each type of radiation, you could look it up in the electromagnetic spectrum. - The wavelength range of ultraviolet light is from $10^{-8}$m (10nm) to $4\times10^{-7}$m (400nm). - The wavelength range of visible light is from $4\times10^{-7}$m (400nm) to $7.5\times10^{-7}$m (750nm). Comparing the wavelength ranges of ultraviolet light and visible light, we conclude that ultraviolet light has shorter wavelengths than visible light. Therefore, the statement is false.
