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).
Ray diagrams are used to show the path that light takes. The rays of light are represented using straight lines, with an arrowhead to show the direction the light is travelling. This diagram shows ...

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...
Ray diagrams are an important tool in understanding the principles of geometric optics. A ray diagram typically uses a simple, straight line to represent a ray of light, with arrows indicating the direction of the light. The diagram may also include labels to indicate the type of optical component being used, such as a lens or mirror.
Ray diagram for an object placed between 2F and F from a convex lens In a film or data projector, this image is formed on a screen. Film must be loaded into the projector upside down so the ...
In a ray diagram, a convex lens is represented as a vertical line segment with two arrows pointing upwards in the extremes In this ray diagram, notice that we have labelled both of the foci as and to allow us to distinguish between each of them. Convex lenses can work in either direction, so if you had a series of parallel light rays hitting the len

May 12, 2022 · Drawing a Ray Diagram. Start by drawing a ray going from the top of the object through the centre of the lens. This ray will continue to travel in a straight line. Next draw a ray going from the top of the object, travelling parallel to the axis to the lens. When this ray emerges from the lens it will travel directly towards the principal focus ...
