A ray diagram is a representation of the possible paths light can take to get from one place to another. This is often from a source or object to an observer or screen. There are a few important things to note: Light travels in straight lines within a uniform medium (this means that light can change direction upon entering a different medium).

In this section of Lesson 5, we will investigate the method for drawing ray diagrams for objects placed at various locations in front of a double convex lens. To draw these ray diagrams, we will have to recall the three rules of refractionfor a double convex lens: 1. Any incident ray traveling parallel to the principal axis of a converging lens wil...
The method of drawing ray diagrams for double convex lens is described below. The description is applied to the task of drawing a ray diagram for an object located beyond the 2F pointof a double convex lens. 1. Pick a point on the top of the object and draw three incident rays traveling towards the lens. 2. Once these incident rays strike the lens,...
In the three cases described above - the case of the object being located beyond 2F, the case of the object being located at 2F, and the case of the object being located between 2F and F - light rays are converging to a point after refracting through the lens. In such cases, a real image is formed. As discussed previously, a real image is formed wh...
Thus far we have seen via ray diagrams that a real image is produced when an object is located more than one focal length from a converging lens; and a virtual image is formed when an object is located less than one focal length from a converging lens (i.e., in front of F). But what happens when the object is located at F? That is, what type of ima...

Learn how to draw ray diagrams for concave mirrors using two rules of reflection and the focal point. Find out how to locate, size, orient, and type the image of an object placed at different positions in front of a concave mirror.
A plane mirror is a flat, smooth reflective surface with a clear, undistorted reflection. When an object is reflected in a plane mirror, it always forms a virtual image that is upright, of the same shape and size as the object. On the other hand, a spherical mirror exhibits a consistent curvature. It possesses a constant radius of curvature (In ...

A ray diagram is a diagram that traces the path that light takes in order for a person to view a point on the image of an object. On the diagram, rays (lines with arrows) are drawn for the incident ray and the reflected ray. Complex objects such as people are often represented by stick figures or arrows. In such cases it is customary to draw ...
