Question

Quizplus · Accepted Answer

Ultraviolet photons have the greatest energy among the options listed. The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Ultraviolet light has a shorter wavelength and higher frequency than visible light (including red, green, and blue light) and infrared light, thus it has the highest energy.
