Question

Apply the Inverse Square Law (to determine the "extraterrestrial solar flux" at the Earth using the Sun's radiant exitancefound in Question 2. Earth (T=300 K) and the Sun (T=5778 K)

d? 02 : G1 6122 where G is the light intensity {or flux) at distance d1, and 62 is the light intensity at distance d2. Ifwe take G as the radiative energy flux at the surface ofthe Sun, we can then estimate the radiative energy flux at the Earth's orbit (62) using this equation simply based on the planetary distances. Try to make this calculation with d1 being the Sun's radius, and d2 being the distance from the Sun to the Earth and see what you get.
