According to Wein's Law,if the surface temperature is increased by a factor of 2,its peak wavelength will:
A) increase by a factor of 2.
B) decrease by a factor of 2.
C) increase by a factor of 4.
D) decrease by a factor of 4.
E) not change; Wein's law has nothing to do with peak wavelength.

Question

Quizplus · Accepted Answer

Wein's Law states that the wavelength of the peak emission of a blackbody radiator is inversely proportional to its temperature. Therefore, if the surface temperature is increased by a factor of 2, the peak wavelength will decrease by a factor of 2.
