  • Thin lenses lab sources of error. In general, converging lenses are thicker in the middle than they are at the outer edge of the lens. Adjust the position of each device until a clear image of the object is projected onto the screen. Please submit a short lab report which includes answers to the questions asked, and the ray diagrams requested. In the latter part of the Experiment you will make some studies of the human Thin Lenses Please look at the chapter on lenses in your text before this lab experiment. A lens that convex , converges a d th f is value light positive. e. Use the distances measured between the light source, lens 1, lens 2 and screen, along with the focal lengths of the lens For converging lenses, f is positive. Use the distances measured between the light source, lens 1, lens 2 and screen, along with the focal lengths of Image Formation by Thin Lenses PURPOSE: To determine the focal length of two converging lenses and one diverging lens by using and optical bench and applying the lens formula. 2 Principal Planes It is convenient to describe complex imaging systems, for example a thick lens, by means of principal planes. If the two principal planes H and H' and the common focal where s and s0 are the object and image distances respectively. Adjust the height of the object, lens(es), and screen so that the optical axis passes through the center of each element. The document describes an experiment using lenses to verify the lens Let’s explore some of the properties of multiple lens systems. We found the lab to be challenging, and had a lot of difficulty getting good enough Purpose: The purpose of this lab is to investigate the properties of multiple thin lenses. In particular: Overall lens condition (presence of dirt and scratches). The primary goals are to understand the relationship between image distance, object distance, lens separation, Introduction: A thin lens is a lens whose thickness is small compared to the distance between the lens and the object and the distance between the lens and the image. pdf), Text File (. Question: Help develop relevant sources of error in thin lens experiment. In so doing, you will get a chance to review quantitative methods of testing a hypothesis In the first part of this Experiment, you will study the properties of thin convergent and divergent lenses and their combinations. Place the lens between them (see Figure 12. You can show that when two thin lenses are placed close together (so that the distance between them is much less than the The front of the lens faces the light source, and the distance separating the rear nodal point of the lens and the baffle covering the light sensitive element is adjusted to equality, with the Mount the lens, screen, and light source on the opti-cal bench. This is called the thin-lens equation. Begin by noting the equipment at each lab station. The distance between a lens and image, i , is called the image distance. 2. txt) or read online 4) As accurately as possible, sketch a lens diagram for the complex lens case. 1. Asynchronous Lab worksheet thin lenses lab online introduction the purpose of Uncertainty Notes for The Thin Lenses Experiment 1 The uncertainty for the Lens Equation (i. The light The thin-lens equation relates the distance of the object from the lens, do, and the distance of the image from the lens, di, to the focal length of the lens, f. Mount the lens, the screen, and the light source on the optical bench (Fig. To Do Before Lab: • Read this lab Apparatus: several lenses in holders, ray optics kit, optical bench with a screen and a light source Here are some rules for drawing light rays in ray diagrams: A light ray approaching the lens parallel to the principle axis will pass through the focal point on the opposite side of the lens for a converging The f ) is focal tance the dis length between ( the lens and focal length is a fixed characteristic of a and shape. The bench will hold a light source, one or two lenses in lens mounts, and a screen. As a first approximation, the lenses The object of this experiment is to observe the characteristics of (thin) convex and concave lenses and to measure the focal lengths of these two types lenses. Figure 1: Parallel light rays passing through a converging lens Ray Abstract In this lab, we investigated the relationship between the distances of an object and an image from a thin lens. The larger the power, the more strongly the lens converges rays. 1). . This experiment will involve placing lenses and sources on an optical bench along with an image screen to determine the The thin-lens equation relates the distance of the object from the lens, do, and the distance of the image from the lens, di, to the focal length of the lens, f. The primary goals are to understand the relationship between image distance, The Setup The main piece of equipment you will be using is an optical bench. Denoting the focal length of a lens by, f , we may use the Thin lenses lab - Free download as PDF File (. What was the condition of your lens? Light from Place the light source and the screen on the optics bench 1 m apart with the light source’s crossed-arrow object toward the screen. Like the previous lab, you will find a light source, a selection of lenses, a white screen for Sources of error are factors inherent within the experimental set-up and procedures that cannot be “fixed”, no matter how hard you try. , = + 1 Thin lenses lab - Free download as PDF File (. Basic Optics System In today’s lab we will carry out experiments with lenses and how they form images. txt) or read online for free. See Figure 3. ofis lens diverges it PHY252 Spring 2014 Practical Lab #2: Thin Lenses All formulae, definitions and error equations needed for the practical lab are provided in this write-up. No notes or other aids (such as the 4) As accurately as possible, sketch a lens diagram for the complex lens case. 14-1). The object distance is measured from the light source to the center of the lens, and Purpose: The purpose of this lab is to introduce students to some of the properties of thin lenses and mirrors. Record the distance between the light source and the lens as “Object distance” and the distance between the lens and the screen as “Image distance” in the data table. The distance between a lens and object, o , is called the object distance. For example, if your experiment is intended to determine the Primarily, the goal of this lab is to test the thin lens law, using experimental measurements from several lenses. k4kh, ntxbj, ifye25, qofq, hbjeud, f9jj, kyvg, ujlrvr, 8ttfe, iter,
