Explain how spectroscopy can be used to determine the elements found within a star:

Answer explanation

Every element has a unique set of wavelengths that it will emit/absorb. Stars emit light and some of that light is absorbed by the star's atmosphere. The wavelengths that are absorbed tell us which elements are present.
