E)A continuous spectrum results when light from a heated elemental substance passes through a prism

Question

Quizplus · Accepted Answer

A continuous spectrum consists of an uninterrupted distribution of colored light, as seen in natural sources like the sun or incandescent light bulbs. Line spectra, on the other hand, are created when light passes through a gas or vapor and only certain wavelengths are emitted, producing distinct lines or bands of color. The dark bands in a rainbow do not correspond to line spectra since they are not produced by the emission of specific wavelengths of light. Neons signs use a gas discharge to produce line spectra, not continuous spectra. Lastly, while heating an elemental substance can produce a continuous spectrum, this is not the only way to do so - it can also be produced by other sources like blackbody radiation or certain types of lasers.
