A blackbody at 200 K is emitting to surroundings. (a)- Calculate the wavelength at which the blackbody emissive power is maximum. (b)- Calculate the energy emitted over the wavelength X=10 to 20 µm (c)- What should the temperature of the blackbody be such that 60% of the total energy emitted lie in the spectrum A=0 to 10 µm ?
