What is the Rayleigh–Jeans law related to?
Black-body radiation
Electromagnetic waves
Quantum mechanics
Thermodynamics
Answer
Black-body radiation is the electromagnetic radiation emitted by a black body, an idealized object that absorbs all incident radiation and emits radiation only due to its temperature. The Rayleigh–Jeans law is a formula that describes the spectral radiance of black-body radiation at long wavelengths, where it predicts that the radiance increases as the fourth power of the wavelength.
