How to Calculate Refractive Index Difference?
Refractive Index Difference calculator uses Difference Refractive Index = (Fringe Displacements Number*Wavelength of Light)/Slab Thickness to calculate the Difference Refractive Index, Refractive Index Difference refers to the change in the refractive index of a medium as measured by observing shifts in the interference fringes in an interferometric setup. Difference Refractive Index is denoted by δn symbol.
