Objective: Carry out high-precision measurements of absorption and emission lines
The resolution of a spectrometer is often assessed in terms of whether the two sodium D-lines can be distinguished. This experiment uses a digital spectrometer with the resolution to do this.
Aditionally recommended: Supplement UE5020150S.
