Ray Diagrams for Convex Lenses - HyperPhysics
Ray Diagrams for Lenses. The image formed by a single lens can be located and sized with three principal rays. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length. The "three principal rays" which are used for visualizing the image location and size are:
24.3: Lenses - Physics LibreTexts
How does a lens form an image of an object? We can use the technique of ray tracing to illustrate how lenses form images. We can also develop equations to describe the images quantitatively. Recall the five basic rules of ray tracing: A ray entering a converging lens parallel to its axis passes through the focal point F of the lens on the other ...
Physics Tutorial: Ray Diagrams - Convex Mirrors - The Physics Classroom
The goal of a ray diagram is to determine the location, size, orientation, and type of image that is formed by the convex mirror. Typically, this requires determining where the image of the upper and lower extreme of the object is located and then tracing the entire image.
Lenses, Ray Tracing, and Simple Optical Devices
We use ray tracing methods to predict the behavior of a lens. We begin with convex lenses, though the same methods apply equally well to concave lenses. There are only three essential premises needed to analyze lenses:
This tutorial explains how to program a simple geometric ray tracing program in MATLAB, which can be written in any other programming language like C or Python and extended to add elements and complexity. The main purpose is that the student understands what …
Ray Diagrams For Converging Lens - Mini Physics
Converging lenses, also known as convex lenses, are thicker at the center than at the edges and cause parallel rays of light to converge (come together) at a point known as the focal point.

Like mirrors, we use ray tracing methods to predict the behavior of a lens. We begin with convex lenses though the same methods apply equally to concave. There are only three essential premises needed to analyze lenses: A light ray entering a lens parallel to the optical axis will pass through the focal point on the other side.
Ray Diagrams for Mirrors - HyperPhysics
Mirror ray tracing is similar to lens ray tracing in that rays parallel to the optic axis and through the focal point are used. A third useful ray is that through the center of curvature since it is normal to the mirror and retraces its path backward. A convex mirror forms a virtual image.The cartesian sign convention is used here.
The oblique (non-perpendicular) ray bends toward the normal (or perpendicular) upon entering the lens, and bends away once it leaves. For a rectangular plate of glass the emerging ray travels a path parallel to the incident ray, but for glass curved inward (concave) or out ward (convex) rays are either diverged
Ray tracing a convex lens: object inside focus The image appears larger (and farther away) than the object. This is a magnifying glass. (Remember: a magnifying glass is a convex lens.) Aside: near-sighted people need concave/diverging lenses; can a …
