The quantity h, now known as the Planck constant, is a universal constant with the approximate value of 6.626 X 10^-34 Js. Max Planck assumed that the radiation energy is emitted in discrete packets called quanta rather than in a continuous way. The energy E of the quantum is related to the frequency Î½ by E = hÎ½.
