Extraordinary refractive index

WebIn general, the refractive indices for non-cubic crys-tals depend on vibration direction. Non-cubic crystals are, therefore, said to be optically ani-sotropic. In most cases the refractive indices for the two rays produced by double refraction are not the same. One of the two rays will have a higher refractive index (and a lower velocity); this WebMay 20, 2016 · Each ray encounters a slightly different electrical environment (refractive index) as it enters the crystal, however, which affects the velocity at which they pass through the crystal. Due to the …
