If the earth were a blackbody with an average temperature of 300 K, determine the wavelength of maximum radiation emitted (µm), the power emitted by the surface of the earth (W/m2), and how much of this power would impinge on a spacecraft orbiting at geostationary altitude (W/m2). (Rheosta= 42,164 km.)
