Problem

Three stars—A, B, and C—are modeled as perfect blackbodies. Their spectra peak at wavelengths of 400 nm, 500 nm, and 700 nm, respectively. Their radii are

0.5\,R_{\odot}

1.0\,R_{\odot}

, and

1.5\,R_{\odot}

, respectively. Rank the stars’ luminosities (total power radiated) from greatest to least. a)

A>B>C

C>B>A

B>A>C

B>C>A
