Planck's law ( by wavelength)
Planck’s law describes the electromagnetic radiation emitted from a black body at a certain temperature. Radiance and spectral radiance are measures
Radiant Exitance (real surface)
In radiometry, radiant exitance is the radiant flux emitted by a surface per unit area, and spectral exitance is the radiant exitance of a surface per unit
Wien's displacement law
Wien’s displacement law states that the black body radiation curve for different temperature peaks at a wavelength that is inversely proportional to
Planck temperature, denoted by TP, is the unit of temperature in the system of natural units known as Planck units.
It serves as the
Compton scattering is an inelastic scattering of a photon by a free charged particle, usually an electron. It results in a decrease in energy (increase in
The Compton wavelength is a quantum mechanical property of a particle. The Compton wavelength of a particle is equivalent to the wavelength of a photon
he Stark–Einstein law is named after German-born physicists Johannes Stark and Albert Einstein, who independently formulated the law between 1908 and 1913.
