Geometric Optics
Geometric optics is the branch of optics that studies light propagation in terms of rays. It simplifies how we understand light by considering it as straight lines traveling through different media, like air or glass. This approach helps explain how lenses focus light, how mirrors reflect it, and how we perceive images. Key principles include reflection (bouncing off surfaces) and refraction (bending as it passes through materials). Geometric optics is fundamental in designing glasses, cameras, and many optical devices, providing insight into how light behaves in various scenarios without delving into the wave nature of light.

Geometric optics is the study of light propagation in terms of rays. It simplifies the behavior of light by tracing straight-line paths, which helps us understand how light interacts with mirrors, lenses, and prisms. This approach is particularly useful for analyzing how images are formed in devices like cameras and eyeglasses. Key concepts include reflection (light bouncing off surfaces), refraction (light bending as it passes through different materials), and the principles governing focal points. While it doesn't consider wave or particle properties of light, geometric optics effectively describes many everyday optical phenomena.
