Question

the light given off by an electric discharge through sodium vapor is ____. white light an emission spectrum of a single wavelength a continuous spectrum

Explanation:

When an electric discharge passes through sodium vapor, sodium atoms emit light at specific wavelengths. This is characteristic of an emission spectrum. White light contains all wavelengths of visible light. A single - wavelength light is too limited (sodium has more than one prominent emission line, though the \(589\) nm doublet is very prominent). A continuous spectrum has all wavelengths in a range without gaps, which is not the case for sodium vapor discharge.

Answer:

an emission spectrum
