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 temperature of a star determines the distribution of light frequencies it emits. Higher temperatures mean more energy is emitted in the form of higher frequencies, which are seen as blue and white light. Cooler stars emit more energy at lower frequencies, which are seen as red and orange light.
