7B11.60 - Spectral Lines/Spectroscopy - "Glo-doodler"
See also 7B11.60 in Astronomy.
Set the equipment up as shown in the picture and position the Glo-doodler over the slit. If desired, only position Glo-doodler over half of the slit so that you can see the continuous white light spectrum and the absorption spectrum at the same time.
