Calculating Air Extinction Coefficient at 275 nm Wavelength

AI Thread Summary
Calculating the extinction coefficient of air at 275 nm wavelength requires specific variables that may not be readily available in existing equations. The Lorentz oscillator model can provide some constraints, although it won't cover all unknowns. Investigating nearby absorption lines could yield rough estimates by analyzing their proximity to the target wavelength and associated transition probabilities. Experimental results may also guide the calculation process. A combination of theoretical models and empirical data is essential for accurate determination.

I'm trying to calculate the extinction coefficient of air at 275 nm wavelength. Can someone help me do this? I can't seem to find enough variables in any equation I've been using to figure it out. Thank you

What have you got so far? Do you have an experimental result that you are trying to match?

Are you familiar with the Lorentz oscillator model? That won't fill in all the unknowns, but it could help you to constrain it somehow. You might try to look up the closest few absorption lines to the wavelength you are looking at, and maybe you obtain some rough estimates based on the distance in wavelength to the resonances and the transition probability.

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...
