Spectra of Sodium Gas Discharge

Spectra of Sodium Gas Discharge

The following image is color coded spectra of sodium undergoing electrical discharge excitation.

It is computed and plotted in your browser by a Java program which reads a file containing a list of emission line wavelengths and their corresponding strenghts.

Note: This program generates deep 24 bit color plots, therefore you may need to increase the color depth of your system to view subtle details in these spectra.

There may be a small delay as each Applet loads its element emission line file and computes the spectra...

Here is a lower quality jpeg of the spectra:
Both neutral and singly ionized sodium contribute to the emission lines in this spectrum.

Sodium Spectra in Two Parts:

from 4000 to 5500 Ångstroms
and from 5500 to 7000 Ångstroms
