Solution of a Modern Physics Problem

Problem 1# When the sun is directly overhead, the thermal energy incident on the earth is
1.4 kWm-2 .Assuming that the sun behaves like a perfect blackbody of radius 7 x 105 km, which is 1.5 x 108 km from the earth, show that the total intensity of radiation emitted from the sun is 6.4 x 107 Wm-2 and hence estimate the sun’s temperature. 85 more words
