An enclosure has an inside area of 50 m2, and its inside surface is black. The enclosure is maintained at a constant temperature. A small opening in the enclosure has an area of 0.01 m2.The radiant power emitted from this opening is 52 W. A. Determine 1) the temperature of the enclosure surface, Ts, in K, 2) total emissive power and 3) total intensity. Hint: the radiant power measured is through the opening area (Ao). B. What is the wavelength l1 below which 10% of the emission is concentrated? What is the wavelength l2 above which 10% of the emission is concentrated?
