At the top of the Earth's atmosphere (1.5 x 10" m away from the centre of the Sun), radiation from the Sun is observed to have a flux density of 1367 W/m². If this radiation is assumed to be emitted from the surface of the Sun, determine the effective temperature of this surface assuming it emits as a black body. The Sun has a radius of 7.0 x 10' m. Assume the radiation propagates uniformly outward from the surface of the Sun so that the total radiant energy crossing any sphere outside the Sun and concentric with the centre of the Sun remains constant.

Transcribed Image Text:At the top of the Earth's atmosphere (1.5 x 10" m away from the centre of the Sun), radiation from
the Sun is observed to have a flux density of 1367 W/m?. If this radiation is assumed to be emitted
from the surface of the Sun, determine the effective temperature of this surface assuming it emits as a
black body. The Sun has a radius of 7.0 x 10' m. Assume the radiation propagates uniformly outward
from the surface of the Sun so that the total radiant energy crossing any sphere outside the Sun and
concentric with the centre of the Sun remains constant.
