Question

Quizplus · Accepted Answer

When light from a hot wire (or any hot, dense object) passes through a cooler gas, the gas absorbs specific wavelengths of light, leading to a line absorption spectrum. This is characterized by dark lines (absorption lines) on a continuous spectrum background, where each line corresponds to a specific element in the gas absorbing light at specific wavelengths.
