Question: Stars located in a certain cluster are assumed to be about the same distance from us. Two such stars have spectra that peak at 1

Stars located in a certain cluster are assumed to be about the same distance from us. Two such stars have spectra that peak at λ1 = 500 nm and λ2 = 700nm, and the ratio of their apparent brightness is l1/l2 = 0.091. Estimate their relative sizes (give ratio of their diameters).
