Problem
The peak wavelength of the emitted radiation from star A is 450nm, whereas that from star B is 650nm. Use these data to answer the following.
(i) Find the ratio TA:TB of the surface temperatures of the two stars.
(ii) If the surface temperature of star B is known to be 4500K, determine the surface temperature of star A.
(iii) Which of the two stars would appear hotter to an observer, and what broad colour would each star most probably exhibit? Justify your answer briefly.
