Question

define Planck's quantum theory

Answer 1

Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T. The law is named after Max Planck, who proposed it in 1900. It is a pioneering result of modern physics and quantum theory.

Answer 2

Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T. The law is named after Max Planck, who proposed it in 1900. It is a pioneering result of modern physics and quantum theory.

The Planck constant is used extensively in physics, especially quantum mechanics. ... This can be shown as h = E/v where "h" is the Planck constant, "E" is the energy of a photon and "v" is the frequency of its associated wave. The Planck constant is therefore measured in units of energy "x" time.
