36 ray diagram for mirror

Ray Diagrams for Mirrors. Mirror Ray Tracing. Mirror ray tracing is similar to lens ray tracingin 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 sinceit is normal to the mirror and retracesits path backward. Index. mirrors. Proceure for Drawing Ray Diagram Step 1 Locate the Image: Draw in the image at the proper location. Step 2 Draw the Reflected Ray: Align a straight-edge along the line of sight. Draw the reflected ray from the mirror to the eye. Extend the reflected ray with a dashed line back to the image location. Step 3 Draw the Incident Ray:

This section of Lesson 2 details and illustrates the procedure for drawing ray diagrams. Let's begin with the task of drawing a ray diagram to show how Suzie will be able to see the image of the green object arrowin the diagram below. For simplicity sake, we will suppose that Suzie is viewing the image with her left eye closed. Thus, we will focus on how light travels from the two extremities of the object arrow (the left and right side) to the mirror and finally to Suzie's right eye as she sights at the image. The four steps of the process for drawing a ray diagram are listed, described and illustrated below. 1. Draw the image of the object. 2. Pick one extreme on the image of the object and draw the reflected ray that will travel to the eye as it sights at this point. 3. Draw the incident ray for light traveling from the corresponding extreme on the object to the mirror. 4. Repeat steps 2 and 3 for all other extremities on the object.

Ray diagram for mirror

A ray diagram shows the path of light from an object to mirror to an eye. Incident rays - at least two - are drawn along with their corresponding reflected rays. Each ray intersects at the image location and then diverges to the eye of an observer. In the first section of Lesson 4, we learned that light is reflected by convex mirrors in a manner that a virtual image is formed. We also learned that there are two simple rules of reflection for convex mirrors. These rules represent slight revisions of the two rules given for concave mirrors. The revised rules can be stated as follows: Some students have difficulty understanding how the entire image of an object can be deduced once a single point on the image has been determined. If the object is merely a vertical object (such as the arrow object used in the example below), then the process is easy. The image is merely a vertical line. This is illustrated in the diagram below. In theory, it would be necessary to pick each point on the object and draw a separate ray diagram to determine the location of the image of that point. That would require a lot of ray diagrams as illustrated in the diagram below. Fortunately, a shortcut exists. If the object is a vertical line, then the image is also a vertical line.
