RAYLEIGH-JEANS LAW

Domain	Definition
Electrical Engineering	Approximate form of Planck's law, obtained by neglecting in the formula for this law the terms of higher order in the series expansion of the exponential. This approximation is valid when(mathematical formula, see IEV)is sufficiently large. Source: European Union. (references)

Specialty Definition: Rayleigh-Jeans law

In physics, Rayleigh-Jeans Law, first proposed in the 19th century, expresses the energy density of blackbody radiation of wavelength λ as

where λ is in meters, T is the temperature in Kelvins, and k is Boltzmann's constant.

The law agrees with experimental measurements for long wavelengths but disagrees for short wavelengths.

Max Planck revised the law, which states:

where h is Planck's constant, c is the speed of light.
