Consider two stars, A and B, of equal size. You take a spectrum of each star and find that the flux of star A peaks at a wavelength of 9000 ̊ A and the flux of star B peaks at 3000 ̊ A. What is the relative luminosities of the two stars? Which star is the hotter one? If star A is at a distance of 10 pc, what distance would star B have to be in order for both stars to appear equally bright as viewed from Earth?
