Light scattering in air. Estimate numerically, using the Lorentz model of the atom, the value of the scattering cross section for molecular nitrogen (N2) for visible light at a wavelength of 500 nm. Use this result to estimate the value of the scattering coefficient R for air at STP. Compare this value with that obtained using Eq. (8.2.22) and the known refractive index of air. (The measured value for 90-degree scattering of unpolarized light, Ru 90, is approximately 2×10^-8 cm^-1.) Also, estimate numerically the attenuation distance of light in air-that is, the propagation distance through which the intensity falls to 1/e of its initial value due to scattering losses
