C)continuous
D)monochromatic

Question

Quizplus · Accepted Answer

When a high voltage is applied to a low-pressure gas causing it to glow, it will emit a line emission spectrum. This is because the energy absorbed by the gas atoms will be re-emitted as light at specific wavelengths corresponding to the electron transitions within the atoms. The resulting spectrum is a series of sharp, discrete lines.
