Answer 1

The absolute color of light emitted by a star is most useful for giving information about the temperature of the star.

Step-by-step explanation:

The absolute color of light emitted by a star is most useful for giving information about temperature of the star. Stars emit different colors of light based on their temperatures. Hotter stars emit bluer light, while cooler stars emit redder light. Therefore, by analyzing the color of light emitted by a star, astronomers can determine its temperature.
