What is radiant flux?
The primary concept is that of the radiant flux of a source, that is, the amount of radiant energy emitted into space in unit time. Usually, we consider only a fraction of the total flux, namely the flux within a relatively small solid angle in the direction of observation, for example, the flux that reaches the dispersing medium or the detecting system.
How to Calculate Absolute Intensity of Atom Line?
Absolute Intensity of Atom Line calculator uses Absolute Intensity of Atom Line = (Gaseous Layer Thickness/(4*pi))*Transition Probability*Neutral Atoms Density*[hP]*Spectral Line Frequency to calculate the Absolute Intensity of Atom Line, The Absolute Intensity of Atom Line formula is defined as the absolute radiant flux emitted, reflected, transmitted or received, per unit solid angle. Measurement of the absolute intensity of a spectral line provides an estimate of the density of an atomic species. Absolute Intensity of Atom Line is denoted by I_{abs} symbol.
How to calculate Absolute Intensity of Atom Line using this online calculator? To use this online calculator for Absolute Intensity of Atom Line, enter Gaseous Layer Thickness (d), Transition Probability (A_{qp}), Neutral Atoms Density (n) & Spectral Line Frequency (ν_{qp}) and hit the calculate button. Here is how the Absolute Intensity of Atom Line calculation can be explained with given input values -> 1.1E-13 = (120000000/(4*pi))*67*780000000*[hP]*340.
