Answer

False. Correction: Ultraviolet light has shorter wavelengths than visible light.

Work Step by Step

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.
