Given two stars, one emits light with a peak wavelength at 400nm (deep blue to your eye) and one emits with a peak wavelength at 600nm (red).
(a) Obtain the temperature of each star.
(b) WHICH star is hotter?
(c) Given the radius of each star is 1.2x109 meters, obtain the total power emitted by each star. Treat each as a perfect emitter.
