Geometric Optics
Definition
Geometric optics is the study of light as rays and how they interact with mirrors, lenses, and other optical devices. It focuses on understanding the behavior of light in terms of straight lines.
Analogy
Imagine you are playing a game of billiards. The way you predict where the balls will go after hitting each other is similar to how geometric optics predicts the path of light rays after interacting with mirrors or lenses.
Related terms
Refraction: Refraction refers to the bending of light as it passes from one medium to another, such as when light enters water from air.
Lens: A lens is an optical device made of transparent material that can focus or diverge light rays by refracting them.
Mirror: A mirror is a smooth surface that reflects most incident light rays, allowing us to see our reflection.
