Quizplus · Accepted Answer

The energy of a photon of light is directly proportional to its frequency and inversely proportional to its wavelength. This is described by the equation E=hf, where E is energy, h is Planck's constant, and f is frequency. It can also be expressed as E=hc/λ, where c is the speed of light and λ is wavelength. Therefore, as frequency increases, energy increases (directly proportional), and as wavelength increases, energy decreases (inversely proportional).
