According to Stefan-Boltzmann law the emittance radiation( R ) is evaluated using the following formula;


"R\\ =\\ \\sigma\\ \\lparen \\dfrac{b}{\\lambda_{max}}\\rparen^4"


"\\sigma=5.67\\ *10^{-8}W\/(m^2K^2)"

"b\\ =2.90\\ *10^{-3}mK\\newline \\lambda_{max}= 500nm"


Substituting we get

"R\\ =5.67\\ *10^{-8}\\ \\ \\lparen\\dfrac{2.9\\ *10^{-3}}{500 nm}\\rparen^4"


"R=6.4\\ *10^7W\/m^2"
