Unformatted text preview: ) at a given temperature T is given by ∞ → = = ∫ ∫ ∞ − ∞ 4 8 ) , ( ) ( d kT d T T U . Classical theory predicts an infinite energy when integrated over all wavelengths! The is refered to as the “ultraviolet catastrophe”! The problem is that every mode is assigned an average energy of kT ( independent of the wavelength ) and the number of modes becomes infinitely large as λ → 0.
