What elements account for these absorption lines seen?
Click For Summary
SUMMARY
The discussion centers on the misinterpretation of absorption lines in spectroscopic images. Participants clarify that the observed vertical lines are not absorption lines but rather artifacts related to the spectrometer's optics. The continuous spectra from both the candle flame and arc flash images lack the narrow dark vertical lines characteristic of true absorption lines. A sharper image is necessary to accurately identify any potential absorption features.
PREREQUISITES- Understanding of spectroscopy and its principles
- Familiarity with continuous spectra and absorption lines

I can't see any absorption lines at all. If you're thinking about the two big black vertical lines, they are not absorption lines, which would be horizontal (at a particular wavelength) in this picture, not cutting across the spectrum. They are probably something to do with the optics of the spectrometer.

The first image is a continuous spectrum . The second image you believe is a continuous spectrum as well ? ...Where am I going wrong, the first image is pointed at candle flame the second is pointed at an arc flash ... wouldn’t there be absorption lines present in the second image ? What accounts for the thick darker regions? :/mjc123 said:

Please don't change your original post (except for minor corrections like typos); now my post seems to make no sense.
What thick darker regions? They both look like continuous spectra. Absorption lines would appear as narrow dark vertical lines. Possibly you haven't got a sharp image of your object, so the spectrum is blurred.
