In optical microscopy, refractive index is an important variable in calculating numerical aperture, which is a measure of the light-gathering and resolving power of an objective. In most instances, the imaging medium for microscopy is air, but high-magnification objectives often employ oil or a si...
refractive index n (General Physics)physicsa measure of the extent to which radiation is refracted on passing through the interface between two media. It is the ratio of the sine of the angle of incidence to the sine of the angle of refraction, which can be shown to be equal to the rati...
There was little difference between the molar refraction values of monomers and that of the repeat unit in the corresponding polymers, in marked contrast to the molar volumes. The ratio of refractive index to molar volume was reasonably consistent for all methacrylates studied (0.25-0.30 ...

. The gas temperature may affect the pressure, and can in addition have an influence on the refractive index via the molecular polarizability, which is typically quite weak. There can also be a dependence on the exact composition; for air, for example, the humidity (H2O content) and the ...
Mathematically, the index of refraction is the ratio of the speed of light through a vacuum and the speed of light through the medium in question. The refractive index can also be calculated by measuring the angle of incidence and the angle of refraction and applying the formula: n = sin(...
Refractive index is much more than a mathematical comparison. It also helps eye doctors find the right lenses tofix refractive errorsand clear upblurry vision. Moreover,high-index eyeglass lensesare manufactured to provide maximum refraction in a thin, lightweight form that is more comfortable and...
