Use the AndersonEggleton relationship to calculate the refractive index of the mineral orthoclase (KAlSi 3 O 8

Question:

Use the Anderson–Eggleton relationship to calculate the refractive index of the mineral orthoclase (KAlSi3O8) with a unit-cell volume 720.4 Å3 containing four formula units. The cation polarizabilities are 1.35 Å3, 0.533 Å3, and 0.284 Å3, for K+, Al3+, and Si4+, respectively. The free-ion polarizability α0 for oxygen is 1.79 Å3 and N0 is 1.776 Å3.
