Astronomers study the spectrum of light emitted by a star to learn about its characteristics. By analyzing the composition of elements, temperature, and density of a star, astronomers can determine its size, age, brightness, and life cycle stage.
Astronomers study spectra to learn about the properties of starts. Spectra (plural of spectrum) is defined as an array of entities, as light waves or particles, ordered in accordance with the magnitudes of a common physical property, as wavelength or mass, and the band or series of colors, together with invisible extensions, produced by dispersion of radiant energy, as by a prism.
