The sun radiates energy at the rate of 6.4xx10^(7)Wm^(-2) . Calculate its temperature assuming it to be a black body.

The sun radiates energy at the rate of 6.4xx10^(7)Wm^(-2) . Calculate

1.	The sun radiates energy at the rate of 6.4xx10^(7)Wm^(-2) . Calculate its temperature assuming it to be a black body.
Answer» SOLUTION :`E = sigmaT^(4) , T = [E/(SIGMA)]^(1//4)` `T = [(6.4xx10^(-7))/(5.67xx10^(-8))]^(1//4)`= 5796 K
