A flame from a match may be approximated as a blackbody at the effective surface temperature of 1830 K, while moonlight may be approximated as a blackbody at the effective surface temperature of 4130 K, respectively. Determine the peak spectral blackbody emissive power for both lighting sources (match flame and moonlight). Given: C1 = 3.74177 × 108 W·μm4/m2 C2 = 1.43878 × 104 μm·K (λT)maxpower = 2897.8 µm·K For a match flame (T = 1830 K), the peak spectral blackbody emissive power, Ebλmax (1830) = _____ × 105 W/m2·µm. For a moonlight (T = 4130 K), the peak spectral blackbody emissive power, Ebλmax (4130) = ______ × 107 W/m2·µm.

Question
A flame from a match may be approximated as a blackbody at the effective surface temperature of 1830 K, while moonlight may be approximated as a blackbody at the effective surface temperature of 4130 K, respectively. Determine the peak spectral blackbody emissive power for both lighting sources (match flame and moonlight).
Given:
C1 = 3.74177 × 108 W·μm4/m2
C2 = 1.43878 × 104 μm·K
(λT)maxpower = 2897.8 µm·K
For a match flame (T = 1830 K), the peak spectral blackbody emissive power,
Ebλmax (1830) = _____ × 105 W/m2·µm.
For a moonlight (T = 4130 K), the peak spectral blackbody emissive power,
Ebλmax (4130) = ______ × 107 W/m2·µm.
