Question

Quizplus · Accepted Answer

When observing a hot, tenuous gas against a dark background, the gas emits light at specific wavelengths corresponding to the energy levels of the atoms or molecules in the gas. This results in an emission line spectrum, where bright lines are seen at these specific wavelengths against a dark background.
