Stosowanie prawa Stefana-Boltzmanna do obliczeń temperatury i mocy w świecie rzeczywistym

Te Stefan- Boltzmann Law opisuje te relacje między nimi, temperature of a blackbody and thee count of energy it radiates. It i s widely use it in physics andd exterering to o estimate thee power radiated by objects based on their temperatur. This articlie explains how to te famy thew for real- terd temperatur te and power callations.
