Consider an incandescent lamp as a black body. The filament made of tungsten achieve a temperature of 2737°C when it is on. During this time, it emits reddish light. Now calculate The peak wavelength of this light. (Points 5) b.The total energy emitted per unit area per unit time. (Points 5) С.The spectral irradiance for this light (Planck's radiation law). (Points 10)
