Geometric optics is a branch of optics that uses rays to describe the behavior of light. This approach is useful for understanding the behavior of light in optical systems, such as:
When light bounces off a surface, such as a mirror. The "Law of Reflection" states that the angle at which light hits a surface (angle of incidence) is equal to the angle at which it bounces off (angle of reflection). Optics For Dummies Pdf
In this article, we'll cover the following key topics in optics: Geometric optics is a branch of optics that
