H emission lines

WebAug 22, 2006 · The H alpha line is flanked by two NII emission lines. Only the very narrow H alpha filters (3nm) can separate Halpha from the NII lines. Therefore most "H alpha" images are actually H alpha + NII images. H beta is an isolated line and allows to record the HII information without interfering other emission lines. #11 jjongmans Vostok 1 Posts: 186 WebAGN Emission Lines - H. Netzer. 11.3. LINERs. LINERs are the least luminous and the most common AGNs. At least 30% of all spirals show this phenomenon and the fraction may even be larger.

The Balmer series is particularly useful in astronomy because the Balmer lines appear in numerous stellar objects due to the abundance of hydrogen in the universe, and therefore are commonly seen and relatively strong compared to lines from other elements. The spectral classification of stars, which is primarily a determination of surface temperature, is based on the relative strength of spectral lines, and the Balmer series in particular is very import… Webyou will measure the He* emission lines in the visible region to gauge the accuracy of the table-top spectrometer that you will use to observe H* emission wavelengths. Using the H* emission data, you will verify n f for the observed emission series and determine an experimental value of the Rydberg constant, R H, graphically.
