D) luminosity

Question

Quizplus · Accepted Answer

Dark-line absorption spectra are specific to each element, and the patterns of dark lines allow scientists to identify which elements are present in the star being observed. Heat and energy may also be measured through spectral analysis, but they do not specifically identify the elements present. Luminosity is a measurement of the brightness of a star and cannot be determined through spectral analysis.
