Direct way of measuring in kelvin the radiation emitted by bodies Author; Rogelio Perez C Summary; Stefan-Boltzmann's law states that the total radiation emitted by a body, E, is proportional to the temperature T, raised to the fourth power of its temperature, (E=σ*A*T ⁴ ), but in order to measure the incoming radiation to a body, and to know the amount of heat it emits, it was not possible to do it directly, so throughout the history of physics we have worked with a theoretical model known as the body black. This model consists of a theoretical object that absorbs all radiant light, for the study of heat emission, this is the same model on which the theory of climate change is based for climate projections, which according to the model will continue to increase, but as the story must be known not to repeat it, it turns out that more than 100 years ago this model produced an error in the temperature measurement results, Known in science as ultraviolet catastrophe, th...
