Which statement correctly compares ultraviolet light to visible light? Ultraviolet light has both a lower frequency and longer w

avelengths than visible light. Ultraviolet light has both shorter wavelengths and a lower radiant energy than visible light. Ultraviolet light has both a higher frequency and longer wavelengths than visible light. Ultraviolet light has both a higher frequency and a higher radiant energy than visible light.

The correct statement is

Ultraviolet light has both a higher frequency and a higher radiant energy than visible light.

because ultraviolet light has wavelength smaller than the visible light hence has a greater frequency as compared to visible light. (frequency is inversely related to wavelength. hence smaller the wavelength , greater will be the frequency)

we also know that the radiant energy is directly proportional to the frequency. hence greater the frequency , greater will be the radiant energy.

Since the frequency is greater for ultraviolet light , it radiant energy is also greater
