Assuming the Sun radiates as a blackbody at a temperature of 5800 K, calculate the expected surface temperature of the Earth, assuming that the Earth also acts as a perfect blackbody. Assume the Earth absorbs an amount of energy proportional to its cross-sectional area, but radiates as a spherical blackbody. If the Earth is in thermal equilibrium with outer space, then the energy received (mostly at visible wavelengths) must equal the amount of energy re- radiated (mostly) in the infrared....
