o surfaces, A and B has a temperature of 4500 K and different spectral ssivity as shown in Figure 3.1. By assuming Stefan Boltzmann constant is 7x 10* W/m-K, determine: the average emissivity for each surface, emissive power for each surface, wavelength of surface A at which spectral emissive power will be a maximum, and which surface is more suitable as a solar absorber? Justify your answer.
