Question

Quizplus · Accepted Answer

The solar lines observed by Fraunhofer were dark absorption lines, which are lines within a spectrum where light has been absorbed by atoms or molecules present in the source of the spectrum. These lines appeared as dark lines on a continuous spectrum because they represented wavelengths of light that were absorbed by the outer layers of the Sun's atmosphere, leaving behind a darker background.
