Optical properties refer to the characteristics of materials that affect their interaction with electromagnetic radiation, particularly light. These properties are crucial in various fields, including physics, materials science, optics, and engineering. Some key optical properties include: 1. **Refractive Index**: This is a measure of how much light is bent, or refracted, when it enters a material. It is defined as the ratio of the speed of light in vacuum to the speed of light in the material.
