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.
Speed of light (in vacuo); c The speed on which electromagnetic radiation propagates within a vacuum; it is described as 299 792 458 m/s.
Regard as an electron and a proton at an instant in time to be at a separation of 5 cm from each other. Presume the pair to be totally isolated from its surroundings in the vacuum
