Emission spectral line intensity

AI Thread Summary
To calculate the intensity of a spectral line, one must consider the energy of the photon released during atomic transitions, which is influenced by factors such as the number of atoms, their excitation state, and the average population of energy levels. The discussion emphasizes the distinction between absolute intensity, which refers to the number of emitted photons over time, and relative intensity. Understanding the Einstein coefficients and energy levels provided by the NIST data is crucial for accurate calculations. Clarification on whether the focus is on relative or absolute intensity is also necessary for precise guidance. Properly addressing these factors will lead to a successful calculation of spectral line intensity.

Dear all

I need to calculate the intensity of the spectral line. I have data from NIST website:
wavelength, Aki (Einstein coefficient), gi, gk, Ei and Ek energy levels.

How do i go about

Thanks for your help

Are you talking about the energy of the photon released from the atomic transition .
 
The intensity of the radiation emitted when an electron transitions from a higher energy state to lower
 
(Absolute) Intensity normally refers to photons per time.
So: how many atoms are there? How are they excited? Do you know the (average) population of the levels? Do you mean relative or absolute intensitiy?
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
