WebAn object at some non-zero temperature radiates electromagnetic energy.If it is a perfect black body, absorbing all light that strikes it, it radiates energy according to the black-body radiation formula.More generally, it is a "grey body" that radiates with some emissivity multiplied by the black-body formula. Kirchhoff's law states that: At thermal equilibrium, … WebMar 6, 2024 · It has been proposed that they emit black-body radiation (called Hawking radiation) with a temperature that depends on the mass of the black hole. The term black body was introduced by Gustav Kirchhoff in 1860. Black-body radiation is also called thermal radiation, cavity radiation, complete radiation or temperature radiation. newly hatched newborn baby hummingbird

"In heat transfer, Kirchhoff's law of thermal radiation refers to wavelength-specific radiative emission and absorption by a material body in thermodynamic equilibrium, including radiative exchange equilibrium. It is a special case of Onsager reciprocal relations as a consequence of the time reversibility of microscopic … See more Before Kirchhoff's law was recognized, it had been experimentally established that a good absorber is a good emitter, and a poor absorber is a poor emitter. Naturally, a good reflector must be a poor absorber. This is why, for … See more In a blackbody enclosure that contains electromagnetic radiation with a certain amount of energy at thermodynamic equilibrium, this "photon gas" will have a Planck distribution of … See more • Kirchhoff's laws (disambiguation) • Sakuma–Hattori equation • Wien's displacement law • Stefan–Boltzmann law, which states that the power of emission is proportional to the fourth power of the black body's temperature See more • Evgeny Lifshitz and L.
