1. Planck's lawnoun

(physics) the basis of quantum theory; the energy of electromagnetic waves is contained in indivisible quanta that have to be radiated or absorbed as a whole; the magnitude is proportional to frequency where the constant of proportionality is given by Planck's constant

1. Planck's law

In physics, Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T, when there is no net flow of matter or energy between the body and its environment.At the end of the 19th century, physicists were unable to explain why the observed spectrum of black-body radiation, which by then had been accurately measured, diverged significantly at higher frequencies from that predicted by existing theories. In 1900, German physicist Max Planck heuristically derived a formula for the observed spectrum by assuming that a hypothetical electrically charged oscillator in a cavity that contained black-body radiation could only change its energy in a minimal increment, E, that was proportional to the frequency of its associated electromagnetic wave. This resolved the problem of the ultraviolet catastrophe predicted by classical physics. This discovery was a pioneering insight of modern physics and is of fundamental importance to quantum theory.

1. planck's law

Planck's law describes the energy distribution of electromagnetic radiation in terms of frequency or wavelength at a certain temperature. It was developed by the German physicist Max Planck in 1900, and is a fundamental principle of quantum mechanics. According to this law, each frequency of radiation has a characteristic temperature at which its intensity reaches a maximum, and then decreases at higher temperatures. The law helps in understanding and calculating the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium.
