This is a comprehensive resource that explains how astronomers use spectra to understand star composition, structure, and evolution. The page begins with an introduction to the electromagnetic spectrum and then goes into great detail about the properties of light. Written on the level of a beginner, it discusses how spectrographs work, absorption and emission lines, and how to interpret the spectral sequence.
This item is part of a larger collection of resources developed for teachers and students of astronomy.
This resource is part of a Physics Front Topical Unit.
