Warm up: Do you think the emission spectrum of Hydrogen is made of a continuous rainbow of colors or a set of individual colored spectral lines? Why?
Hint: review your notes and your worksheet on the Hydrogen electronic transmissions, especially the Balmer Series.
These pictures show the difference between continuous, emission and absorption spectra.
Why is the absorption spectrum the opposite (compliment) of the emission spectrum?
Study these specra before looking at the spectra from the gas discharge tubes.
In the space below, draw the emission lines for H, He and Hg using colored pencils.
Now look at the emission lines of the gas discharge tubes and put Czech marks on your drawing above each spectral line you were able to see.
