Quizplus · Accepted Answer

Red light has less energy per photon compared to blue light. This is because the energy of a photon is directly proportional to its frequency (E = hf), and inversely proportional to its wavelength. Red light has a longer wavelength and lower frequency than blue light, thus it has less energy per photon.
