A flat opaque, diffuse and nongray surface has a spectral emissivity as shown in the figure below. Radiant energy is incident on the flat surface from the surroundings, which may be considered as black and at a temperature T = 1500K. If the temperature of the flat surface is T. = 500K, compute both its absorptivity a and emissivity . 7,5 1 0.75 0.5 0.25 0 2 4 6 8 {TSUY = 1500K, E=1 Flat Surface T = 500K
