The spectra of most stars are of this type.

Question

Quizplus · Accepted Answer

The majority of stars have a dark-line (absorption) spectrum, where certain wavelengths of light are absorbed by the elements in the star's atmosphere, creating dark lines in the spectrum. This is in contrast to a bright-line (emission) spectrum, where certain wavelengths are emitted by the elements in a hot, ionized gas. A continuous spectrum is generated by a hot, dense object like a blackbody radiator, and is not typically observed in stars. Therefore, B is the best choice for this question.
