Question

which information about objects in space can spectroscopy provide? select the two correct answers. (1 point)

□ composition

□ timing of solar flares

□ temperature

□ size

Explanation:

Spectroscopy analyzes the light emitted/absorbed by celestial objects. Unique spectral lines reveal the chemical makeup (composition) of the object. Additionally, the intensity and shift of spectral lines can be used to calculate the object's temperature. Solar flare timing is tracked via other observational methods, and size is determined through techniques like angular measurements or gravitational lensing, not spectroscopy.

Answer:

• composition
• temperature
