Problem
Astronomers observe that the wavelengths corresponding to maximum intensity in the spectra of two distant stars are 450 nm and 600 nm respectively. Assuming both stars behave like perfect blackbodies and have identical radii, calculate the ratio of the power radiated per unit area by the hotter star to that of the cooler star. Express your answer correct to two significant figures.
