Crystal refractive index
WebRefractive Index – the crystal should have a higher index of refraction than the sample. The majority of organic samples have refractive indices in the area of 1.5. Refractive … WebA wave’s velocity through a crystal is described by the crystal’s refractive index ( n ), which depends on chemical composition, crystal structure, and bond type in the crystal. The refractive index ( n) is the ratio of the …
