How can I use MIE scattering to determine the best particle size to light scattering with glasses?

There is a simple algebraic formula relating turbidity to optical properties. You do not need Mie theory. It is given in van de Hulst "Light scattering from small particles" (a nice cheap reprint from Dover Press). More easily accessible are any of the Mie calculators avaiable on the Internet, say Miecalc, these will give the exact result.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
