Problem

Star A and Star B behave like ideal blackbodies. Star A shows a peak emission at

450\,\text{nm}

, while Star B peaks at

600\,\text{nm}

. If the radius of Star A is twice that of Star B, what is the ratio of the total power radiated from the entire surface of Star A to that of Star B? a)

\dfrac{64}{9}\,(\approx 7.1)

\dfrac{1024}{81}\,(\approx 12.6)

\dfrac{256}{81}\,(\approx 3.2)

\dfrac{512}{81}\,(\approx 6.3)
