Star A's spectrum is most intense at 500 nm,while star B's spectrum is most intense at 750 nm.If star A has a temperature of 5,800 K,what is the temperature of star B?
A) 13,000 K
B) 8,700 K
C) 4,500 K
D) 3,850 K

Question

Quizplus · Accepted Answer

According to Wien's Law, the peak wavelength is inversely proportional to the temperature. If star A's peak is at 500 nm with a temperature of 5,800 K, then star B's peak at 750 nm will have a lower temperature. Using Wien's Law, T = (2.898 x 10^6 nm*K) / wavelength, star B's temperature is approximately 3,850 K.
