Quizplus · Accepted Answer

A common light bulb produces a continuous spectrum, which means it emits light at all wavelengths within the visible spectrum. This is in contrast to a bright-line emission spectrum, which only shows specific bright lines at certain wavelengths, or a dark-line absorption spectrum, which shows specific dark lines where certain wavelengths have been absorbed.
