I assume that the density of air will come into play as there will be more scattering and so will the distance but I can't find any equations or even begin to derive my own.

Thanks

Rayleigh scattering would be the primary source of loss at short wavelengths. Rayleigh scattering is indeed dependent on the particle density;

The scattering cross section is related to the linear loss the exponential relationship P = P_0*e^(-/sigma*x).

That does the job, I can now make the calculations I wanted.. Thank you
