It is shown that a formula for the intensity of optical emission lines is in very good agreement with experimental results reported in standard tables of spectral data. It is emphasized that the formula is consistent with main features of the spectrum of the Sun. The formula is: I(h nu) ...
An empirical formula for the wave numbers of various lines of certain spectral series such as neutral hydrogen and alkali metals; it states that the wave number of thenth member of the series is λ∞-R/(n+a)2, where λ∞is the series limit,Ris the Rydberg constant of the atom, andais...

I have a question about NX motion. I want to move a component both upward and downward, but when I use the math function in the joint command (as shown in the attached image), the component only moves upward. How can I resolve this? Regards Santhosh ...
Once inured to the habit of accurately imagining abstract relations, recognizing the true value of symbolic conceptions, and familiarized with a fixed standard of proof, the mind is equipped for the consideration of quite other objects than lines and angles. The twin treatises of Adam Smith on ...
Polarisation of Spectral Lines Polarisation effects can be associated with the lines related to Zeeman splitting. Polarisation in this context refers to the direction of the vibration of electromagnetic field lines. For example, polarising sunglasses usually suppress ambient glare because light reflected fr...
n.A formula, similar to that of Balmer, for expressing the wave-numbers (v) of the lines in a spectral series: wherenandmare integers andm > n,a, andbare constants for a particular series, andRis theRydberg constant, 109,667.8 cm−1for hydrogen. ...
5043. A semi-empirical formula to describe the net emission coefficient of self-absorbed spectral lines for use in modelling high-pressure discharge lamps : B F Jones and D A J Mottram, J Phys D: Appl Phys, 14 (7), 1981, 1183–1194...
A novel feature in the lines of research by Vassiliev and his collaborators [35, 36] is the second term of the Weyl law (see the references cited in these papers for earlier works). Analogous results have been achieved by Li–Strohmaier [37] employing a different spectral analysis. ...
The dashed lines in (b,d) indicate the calculated decay lengths using Eq. (3). The x = y line is shown in (e,g) as the dashed line for clarity. The photocurrent profiles in (a,c) are offset vertically for clarity. Full size image Now we will apply the analytical model to ...
