The two laes I studied are Wien's law and Boltzmann's Law and here I'll explain each of them
He realized that that the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature. This is the formula to calculate the temperature: T=(2.9*10^6 k*m)/λmax
Stefan-Boltzmann establishes statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature, this is his formula: L=σT^4·4πR^2 where L is the luminosity,σ the constant and 4πR^2 the star surface onda
