The Stefan Boltzmann law is the total amount reflected per unit area along all wavelengths. It can be obtained after interconnecting Plank’s radiation formula. Then, it becomes: dP/dλ.1/A = 2πhc2/λ5 (hc/eλkT – 1) In the above equation, P = Radiated power. A = Total area of black body. 網頁Thermal diffusion coefficients vs. temperature, for air at normal pressure.
