Planck's Law (Noun)
Meaning
(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.

Examples
- Planck's law describes the distribution of energy in the electromagnetic radiation emitted by a black body at a specific temperature.
- The energy of a photon, according to Planck's law, is directly proportional to the frequency of the electromagnetic wave.
- In deriving Planck's law, Max Planck introduced the concept of quantized energy, fundamentally changing the understanding of classical physics.
- The predictions made by Planck's law have been consistently confirmed by experiments, further solidifying its importance in quantum theory.
- Max Planck's work on black-body radiation led to the establishment of Planck's law, laying the groundwork for modern quantum mechanics.
