## Main Question or Discussion Point

Hello everyone, I'm not sure if this is in the correct topic, so please move to a correct one if need be.

Are there any mathematical relationships between the wavelength or frequency of an electromagnetic ray and the optical properties of a material?

By optical properties, I mean the scattering coefficient ([itex]\mu_s[/itex]), absorption coefficient ([itex]\mu_a[/itex]), and anisotropy factor (g).

i.e. [tex]f(\lambda or f) = stuff and \mu_s[/tex], etc.

Preferably, there would be only one equation, which governs all types of emr's and materials, but I don't know if there is such thing.

If not, literature pointing to similar things would be great too!

Thanks
