Chapter 11 Fundamentals of Thermal Radiation 11-21 The temperature of the filament of an incandescent light bulb is given. The fraction of visible radiation emitted by the filament and the wavelength at which the emission peaks are to be determined. Assumptions The filament behaves as a black body. Analysis The visible range of the electromagnetic spectrum extends from λ μλ μ 12 040 076 = = . m to . m . Noting that = 3200 K, the blackbody radiation functions corresponding to T λ λ 1 T and 2 T are determined from Table 11-2 to be
