Explanation:
Detailed explanation-1: -By seeing which colors are emitted or absorbed, and the relative amounts of each wavelength, astronomers can identify the chemical composition of a star’s atmosphere or an interstellar nebula, along with the temperature and pressure of the gas. Astronomers also use known spectra to measure the distance to galaxies.
