Presentation
Extinction and scattering spectra can be calculated from this page using the Mie theory. The sphere dimension and composition and the refractive index of the embedding medium can be chosen. Qextinction and Qscattering are calculated and are respectively the extinction and scattering cross-sections divided by πR2 where R is the radius of the sphere.
You can zoom the plot by selecting a rectangle and zoom out using
