Planck relation

The Planck relation^[1]^[2]^[3] (referred to as Planck's energy–frequency relation,^[4] the Planck–Einstein relation,^[5] Planck equation,^[6] and Planck formula,^[7] though the latter might also refer to Planck's law^[8]^[9]) is a fundamental equation in quantum mechanics which states that the energy $E$ of a photon, known as photon energy, is proportional to its frequency $ν$ :

The relation accounts for the quantized nature of light and plays a key role in understanding phenomena such as the photoelectric effect and black-body radiation (where the related Planck postulate can be used to derive Planck's law).
