Description:

KNOWN: Solar flux at outer edge of earth's atmosphere, 1353 W/m2.

FIND: a) Emissive power of sun.

b) Surface temperature of sun.

c) Wavelength of maximum solar emission.

d) Earth equilibrium temperature.

ASSUMPTIONS: 1) Sun and earth act as blackbodies.

2) No attenuation of solar radiation en route to earth.

3) Earth atmosphere has no effect on earth energy balance.

ANALYSIS: Applying conservation of energy to the solar energy crossing two concentric spheres, one having the radius of the sun and the other having the radial distance from the edge of the earth's atmosphere to the centre of the sun.
