Question

Quizplus · Accepted Answer

Typical stellar spectra appear as a rainbow, but with some dark lines mixed in. These dark lines, known as absorption lines, correspond to specific wavelengths of light that are absorbed by the elements present in the star's atmosphere. The positions and intensities of these lines can provide insights into the chemical composition and physical properties of the star.
