Lens Focusing Principle: Ray Diagram and Wavefront Convergence #197342 (License: Personal Use)

This 3D schematic shows parallel light rays entering a convex lens (represented by the blue cone), refracting, and converging toward a focal point on the right, where a green sphere depicts the formed image. Spherical wireframe wavefronts illustrate phase progression before and after refraction, while the angle θ indicates the angular spread of the focused beam. The clean vector-style rendering emphasizes optical principles used in camera lenses, telescopes, and microscopy.

Used in educational physics or engineering web pages explaining geometric optics, lens design, or imaging systems; targets students, educators, and hobbyists seeking intuitive visualizations of focal length and wavefront behavior.
