Wavelength difference of sodium d lines?

AI Thread Summary
The discussion centers on finding the wavelengths of sodium D lines, specifically D1 and D2. Users suggest searching online, with one recommending the website http://steck.us/alkalidata/ for relevant data. Another participant mentions that a simple Google search for "sodium d lines" yields useful results, including a Wikipedia entry. There is a suggestion to be more specific in searches if the desired information is not found. The conversation highlights the importance of precise queries when seeking scientific data online.

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?

Thread 'Question about pressure of a liquid'

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
