refractive index | Definition & Equation | Britannica
2020/8/8· Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index n

Laboratory chaer measurements of the longwave …
Data are used in coination with particle size distributions to estimate the complex refractive index of each dust sample. Our results show that the magnitude and spectral dependence of the dust extinction and refractive indices differ according to particle mineralogy, suggesting the necessity for regionally resolved optical properties for modeling dust radiative effects in the longwave.

Moissanite Vs. Diamonds
Moissanite is known for its refractive index of 2.65, which is notably higher than a diamond at 2.42 or sapphire at 1.76. The higher the refractive index, the higher the brilliance, which looks like bright light traveling out of the stone. One of the most visibly

Moissanite, Information & history of moissanite gemstones
Moissanite''s very high refractive index ("fire") also allows Moissanite to better retain it''s fire if it gets dirty, oily, or smudged, (unlike CZs that look very dull when dirty). These color/clarity characteristics are another reason that Moissanite looks like a diamond & not like a Cubic Zirconia (CZ).
