16) This is used to determine how light bends in glass for analysis: A) Refractive Index B) Shift Fractures C) Glass Refractive Index Measuremen (GRIM), D) Both A and C

The correct answer is D) Both A and C.<br /><br />The refractive index is a measure of how much light bends when it passes through a medium, such as glass. It is an important property in the analysis of optical materials and devices. Glass Refractive Index Measurement (GRIM) is a technique used to determine the refractive index of glass.<br /><br />Therefore, both the refractive index and GRIM are used to determine how light bends in glass for analysis.
