Physical Governing Equations
Stefan-Boltzmann Law
P = ε · σ · A · T⁴
Wien's Displacement Law
λ_max = b / T (where b ≈ 2,898 µm·K)
Radiant Emittance
E = P / A = ε · σ · T⁴
Stefan-Boltzmann constant σ ≈ 5.6704 × 10⁻⁸ W/(m²·K⁴).
Total power emitted is proportional to the 4th power of absolute temperature.
