Ultraviolet catastrophe:
A shortcoming of the Rayleigh-Jeans formula, that tries to explain the radiancy of a blackbody at several frequencies of the electromagnetic spectrum. It was obviously wrong since as the frequency enhanced, the radiancy enhanced without bound; something quite not observed; it was dubbed the "ultraviolet catastrophe." It was later on reconciled and described by introduction of the Planck radiation law.
