Why does a star's color corresponds to its temperature?
A)Higher temperature means more energetic light, which is seen as higher frequencies.
B)because of the light shifts that take place when star light interacts with the Earth's atmosphere
C)because the core temperature averages with the surface temperature to create an overall color
D)because the ultraviolet output of a star directly modifies the visible light spectrum the star is emitting

Question

Quizplus · Accepted Answer

The color of a star is determined by its temperature due to the fact that higher temperatures result in the emission of more energetic light, which corresponds to higher frequencies on the electromagnetic spectrum. Cooler stars emit light at lower frequencies, which appear to us as redder colors, while hotter stars emit light at higher frequencies, appearing bluer. This relationship is described by Wien's displacement law.
