### Atomic Spectra Pre-Assessment #13

What is the difference between absorption line and emission line spectrum?

They technically provide the same data. Absorption line spectra display the wavelengths of light absorbed, and emission line spectra display the wavelengths of light emitted. You can measure either to get the same information, it just depends on what experimental tools were available.
