FLASHCARD QUESTION

Front

What does the spectrum of a star indicate?

Back

The spectrum of a star indicates its composition, temperature, density, mass, distance, luminosity, and relative motion.

FLASHCARD QUESTION

Front

What is the difference between emission and absorption spectra?

Back

Emission spectra are produced when atoms emit light at specific wavelengths, while absorption spectra occur when atoms absorb light at specific wavelengths.

FLASHCARD QUESTION

Front

How do older stars differ from younger stars in terms of element fusion?

Back

Older stars have been fusing elements longer and have typically run low on hydrogen, leading them to fuse heavier elements.
