Ray Geometry

Ray geometry is a way of describing how light travels as it moves in straight lines called rays. A ray starts at a specific point, called the origin, and extends infinitely in one direction. It's used in optics to analyze how light interacts with lenses, mirrors, and other objects. Instead of thinking about light as a wave, ray geometry simplifies light's path to straight lines, helping us predict how images form, how reflections occur, and how lenses focus light. This approach is fundamental in designing optical devices and understanding visual phenomena.
