WebJohn Strutt, Lord Rayleigh and James Jeans Ultraviolet Catastrophe. A blackbody is an idealized object which absorbs and emits all frequencies. Classical physics can be used to derive an equation which describes the intensity of blackbody radiation as a function of frequency for a fixed temperature — the result is known as the Rayleigh-Jeans law.
