Refractive index of crystalline solids
WebThe physical properties of crystalline solids like refractive index, coefficient of thermal expansion, electrical and thermal conductivities are sometimes anisotropic in nature for some crystals. WebNov 13, 2015 · Optical Birefringence. Birefringence is formally defined as the double refraction of light in a transparent, molecularly ordered material, which is a manifestation of the existence of orientation-dependent differences in refractive index. Many transparent solids are optically isotropic, meaning that the index of refraction is equal in all ...
