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 'Gauss' law seems to imply instantaneous electric field propagation'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...

Thread 'A scenario of non-uniform circular motion'

(All the needed diagrams are posted below) My friend came up with the following scenario. Imagine a fixed point and a perfectly rigid rod of a certain length extending radially outwards from this fixed point(it is attached to the fixed point). To the free end of the fixed rod, an object is present and it is capable of changing it's speed(by thruster say or any convenient method. And ignore any resistance). It starts with a certain speed but say it's speed continuously increases as it goes...
