1. Pick a point on the top of the object and draw three incident rays traveling towards the lens. Using a straight edge, accurately draw one ray so that it passes exactly through the focal point on the way to the lens. Draw the second ray such that it travels exactly parallel to the principal axis. Ray diagrams have been a valuable tool for determining the path taken by light from the object to the mirror to our eyes. In this section of Lesson 3, we will investigate the method for drawing ray diagrams for objects placed at various locations in front of a concave mirror.

(a) Light reaches the upper atmosphere of Earth by traveling through empty space directly from the source (the Sun). (b) This light can reach a person in one of two ways. It can travel through a medium, such as air or glass, and typically travels from one medium to another. It can also reflect from an object, such as a mirror. A ray diagram is a tool used to determine the location, size, orientation, and type of image formed by a lens. Ray diagrams for double convex lenses were drawn in a previous part of Lesson 5. In this lesson, we will see a similar method for constructing ray diagrams for double concave lenses. Step-by-Step Method for Drawing Ray Diagrams The changing of a light ray's direction (loosely called bending) when it passes a boundary between materials of different composition, or between layers in single material where there are changes in temperature and density, is called refraction. 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 a ray diagram, rays of light are drawn from the object to the mirror, along with the rays that reflect off the mirror. The image will be found where the reflected rays intersect. Note that the reflected rays obey the law of reflection. What you notice is that the reflected rays diverge from the mirror; they must be extended back to find the. A completed ray diagram is shown in; The angle in which a light ray hits the mirror is the same angle in which it will be reflected back. If, for example, a light ray leaves the top of an object travelling parallel to the principal axis, it will hit the mirror at a 0 degree angle, and be reflected back at 0 degrees. A ray diagram shows how light travels, including what happens when it reaches a surface. In a ray diagram, you draw each ray as: a straight line; with an arrowhead pointing in the. By examining the ray diagram of a spherical mirror, we can gain insights into the fascinating phenomena of reflection and image formation. Table of Contents What is a Mirror?

This physics video tutorial on optics provides a basic introduction into ray diagrams. It explains how to draw ray diagrams for converging lens, diverging lens, concave mirrors, and convex. A ray diagram shows the path of light from an object to mirror to an eye. A ray diagram for a convex mirror shows that the image will be located at a position behind the convex mirror. Furthermore, the image will be upright, reduced in size (smaller than the object), and virtual. This is the type of information that we wish to obtain from a ray diagram.
Yes, you can draw different rays of light when creating the ray diagram. For example, you can draw a ray of light parallel to the principal axis which reflects off the mirror and passes through the principal focus (like in this video). But also, you can draw a ray of light that passes through the principal focus (on its way to the mirror) and. Figure 25.3.3 25.3. 3: The change in direction of a light ray depends on how the speed of light changes when it crosses from one medium to another. The speed of light is greater in medium 1 than in medium 2 in the situations shown here. (a) A ray of light moves closer to the perpendicular when it slows down.

AboutTranscript. This video explores the concept of convex lenses, focusing on how they refract and transmit light. The instructor explains the behavior of light as it passes through a lens, using the analogy of a car to illustrate refraction. The video also introduces the idea of a lens's focal point and the thin lens assumption. How does a lens or mirror form an image? See how light rays are refracted by a lens or reflected by a mirror. Observe how the image changes when you adjust the focal length of the lens, move the object, or move the screen.
