8. For a dia tomic molecule of polarizability a(w) under a near-infrared monochromatic plane wave E= Eosin (wt-kx)a, (a) Find the time-averared differential radiation power into differential solid angle d. In which direction is the radiation strongest? weakest? ( (b) If the density of the molecule is N, what percentage of EM wave will be scattered per unit length? (Assume low-density molecules in vacuum and ignore any interference effect between them.)
