According to the formula E=hf (where E is the energy of a photon, h is Planck's constant, and f is the frequency of light), the energy of a photon is directly proportional to its frequency. Since frequency and wavelength are inversely related, it follows that the energy of a photon is inversely proportional to its wavelength. Therefore, as the wavelength of light decreases, the energy per photon increases, and vice versa.
