Convex Lens Refraction Diagram - Light Focusing Principle #1210934 (License: Personal Use)

This schematic illustrates the refraction of parallel incident light rays (red) as they pass through a plano-convex orange lens, bending due to the change in refractive index and converging toward a focal point. The cyan rectangle below represents a detector plane or aperture where the focused beam would intersect; the diagram emphasizes geometric optics principles used in cameras, microscopes, and eyeglasses.

Used in educational content about optics, physics textbooks, STEM lesson plans, or technical documentation for optical devices; targets students, educators, and engineers seeking to understand lens behavior and focal properties.
