Define stefan's law of radiation
WebStefan–Boltzmann Law. Radiation heat transfer rate, q [W/m 2], from a body (e.g., a black body) to its surroundings is proportional to the fourth power of the absolute temperature.It can be expressed by the following equation: q = εσT 4. where σ is a fundamental physical constant called the Stefan–Boltzmann constant, equal to 5.6697×10-8 W/m 2 K 4.The … WebQuantitatively, Wien’s law reads. λ max T = 2.898 × 10 −3 m · K. 6.1. where λ max is the position of the maximum in the radiation curve. In other words, λ max is the wavelength at which a blackbody radiates most strongly at a given temperature T. Note that in Equation …
