Hello everyone , I googled for it but nothing came up, Where can I find that?
Thanks in Advance ,
Search harder! Then you will find the answer in http://steck.us/alkalidata/
I looked at data tables , but there was nothing about sodium spectrum :(
See tables 3 and 4 for the wavelengths in air for the sodium D1 and D2 lines.
When you say, "I googled for it but nothing came up," what do you mean? When I typed "sodium d lines" into Google, the very first entry was a Wikipedia page with the wavelength of the sodium D1 and D2 lines. What did you type in?
If you didn't find what you were looking for in there, maybe you should be more precise about what you what you want.
Another good source of data is http://physics.nist.gov/PhysRefData/Handbook/Tables/sodiumtable1.htm
Separate names with a comma.
