Term: Planck's Radiation Law

Description:

Planck's Radiation Law, also known as Planck's blackbody radiation law, is a fundamental principle in quantum physics that describes the distribution of electromagnetic radiation emitted by a perfect black body. It establishes the relationship between the wavelength of the radiation and the temperature of the emitting body.

Senses:

Sense 1 - Concept:

Planck's Radiation Law states that the intensity of radiation emitted by a black body at a given wavelength and temperature follows a specific distribution.

Example sentence: According to Planck's Radiation Law, the energy of a photon is directly proportional to its frequency.

Sense 2 - Practical Application:

Planck's Radiation Law is widely used in astrophysics, quantum mechanics, and the study of thermodynamics.

Example sentence: By applying Planck's Radiation Law, scientists can determine the temperature of stars based on their observed spectral energy distribution.
