Question

Quizplus · Accepted Answer

As a blackbody becomes hotter, it emits more energy and becomes more luminous. At the same time, the peak wavelength of its emission spectrum shifts to shorter wavelengths, which means it becomes bluer. This is described by Wien's Law, which states that the peak wavelength of a blackbody's emission spectrum is inversely proportional to its temperature. Therefore, choice B is the best answer.
