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. AssumptionsThe filament behaves as a black body.AnalysisThe visible range of the electromagnetic spectrum extends from λμλμ12040076==.m to .m . Noting that = 3200 K, the blackbody radiation functions corresponding to Tλλ1Tand 2Tare determined from Table 11-2 to be
