Spectral lines are useful in classifying stars because they show the composition of a star. Each star has a unique spectrum that corresponds to the elements present in its atmosphere. By analyzing the spectral lines, scientists can determine the chemical composition of a star, including the abundance of various elements. This information helps in categorizing stars into different spectral types and understanding their evolutionary stages.
