conclusion question #2

1. how can light spectra be used to determine what elements a star contains?

Explanation:

Each element has a unique spectral fingerprint. When light from a star passes through a spectroscope, it is split into a spectrum. Dark or bright lines in the spectrum correspond to the absorption or emission of light at specific wavelengths by elements in the star. By comparing these lines to known spectral patterns of elements, we can identify the elements present in the star.

Answer:

Each element has a characteristic spectral pattern. By analyzing the absorption or emission lines in a star's light spectrum and comparing them to known element - specific patterns, we can determine the elements in the star.
