Consider a particle cloud with a distribution function of n(a) = Ca2
e
−ba, where a is particle radius
and b and C are constants. The particles are coal (ǫ = 1), and measurements show the particles
occupy a volume fraction of 1%, while the number density has been measured as NT = 106
/cm3
.
Calculate the extinction, absorption, and scattering coefficients of the cloud for the wavelength range
