WebMany minerals exhibit birefringence, which is a directional dependence of the speed of light through the mineral.This phenomenon is used by petrologists to identify minerals in a thin section (≤ 1 mm) where a sample illuminated by polarized light is rotated under a microscope to reveal its birefringence. Likewise, elastic waves show a directional … WebBirefringence is determined by a family of lines that emanate radially from the origin, each with a different measured value of birefringence corresponding to thickness and interference color. The Michel-Levy chart …
