Blackbody fraction
WebTable 2.4 presents a tabulation of E b (0 → λT) as a fraction of the total emissive power, E b = σT 4, for various values of λT, also called fraction of radiation emitted from a blackbody at temperature T in the wavelength band from λ = 0 to λ, f 0-λT or for a particular temperature, f λ. WebWhat fraction of the emission from a blackbody at 5800 K lies in the visible range of the electromagnetic spectrum, i.e., in the range from 0.4 to 0.8 μm? Solution. There are different ways to solve this problem. We will first solve it using Table 9.1. The fraction in the band from λ 1 = 0.4 μm to λ 2 = 0.8 μm is F 0 → λ 2 T − F 0 → ...
