How To Draw A Ray Diagram

Draw the second ray such that it travels exactly parallel to the principal axis. Using a straight edge accurately draw one ray so that it passes exactly through the focal point on the way to the mirror.

The Reflection And Refraction Of Light

Concave mirror use the following laws.

How to draw a ray diagram. Complex objects such as people are often represented by stick figures or arrows. This section of lesson 2 details and illustrates the procedure for drawing ray diagrams. 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 basic ray diagram. It isnt a real part of the ray diagram the rays we draw change direction when they cross the single vertical line.

Initially we have an object in front of a plane mirror. It explains how to draw ray diagrams for converging lens diverging lens concave mirrors and convex mirrors. Draw a ray diagram to show how such a lens would work.

Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principle axis upon reflection. Pick a point on the top of the object and draw two incident rays traveling towards the mirror. This physics video tutorial on optics provides a basic introduction into ray diagrams.

Between the lens and the focal point. You need to label both the object and image in your diagram and to think about where the image appears to be. Shows how to draw ray diagrams to locate the image formed by a convex lens.

Yet the same method works for drawing a ray diagram for any object location. From the top of the object draw two rays such that one ray passes through the focal point if produced while the other travels straight towards the mirror and is parallel to the principal axis. Click on the images to view a larger version.

Any incident ray travelling parallel to principle axis on the way to the mirror will pass through the focal point upon reflection. Secondly we draw the lens. To draw a ray diagram of.

Distance a is equal to distance b and the image size is the same size as the object size. We draw the lens as a single vertical line. On the diagram rays lines with arrows are drawn for the incident ray and the reflected ray.

This is a short tutorial on how to draw ray diagrams for plane mirrors. Draw a basic ray diagram and choose a point to mention the object. Drawing ray diagrams a step by step approach.

Often we also draw an outline showing the shape of the lens but this is only to remind us whether the lens is a converging lens or a diverging lens. First we draw an image of the object on the other side of the mirror. For a magnifying lens to work the object is placed close to the convex lens ie.

In such cases it is customary to draw rays for the extreme positions of such objects. You can see a listing of all my videos at my website httpwwwstepbystepscienc.
