The Stefan - Boltzmann law describes the power radiated from a black body: a) S=klnW b) varepsilon =(3)/(2)kT c) R=sigma T^4 d) E=hv Bbl6epure oAMH OTBeT: b) a) C) d)

The correct answer is c) .The Stefan-Boltzmann law states that the total energy radiated per unit surface area of a black body is directly proportional to the fourth power of its absolute temperature. This can be expressed mathematically as: where:- is the total energy radiated per unit surface area (in watts per square meter, W/m²)- is the Stefan-Boltzmann constant, approximately equal to W/m²K⁴- is the absolute temperature of the black body (in Kelvin, K)The other options are not correct:a) is not the Stefan-Boltzmann law.b) is not the Stefan-Boltzmann law.d) is the Planck-Einstein relation, not the Stefan-Boltzmann law.
