If the sun’s surface radiates heat at

6.3 \times {10^7}W{m^{ - 2}}

. Calculate the temperature of the sun assuming it to be a black body

\left( {\sigma = 5.7 \times {{10}^{ - 8}}W{m^{ - 2}}{K^{ - 4}}} \right)

View answer and explanation

Correct option: A

5.8 \times {10^3}K

The correct answer is A (

5.8 \times {10^3}K

) because it is the temperature calculated using Stefan's law, assuming the sun is a black body.
