Assuming the earth is a blackbody with an average surface temperature of 14°C, what is its emissive power (in W/m2 -µm) at the mid microwave band of 105 µm? If the wavelength band for microwaves is 104-106µ,m, very approximately how much (in W/m2 of earth's surface) microwaves would earth emit? (Hint: The blackbody radiation function in the text does not have tabulated values for this wavelength range.)
