Pre-Lab 12 Ray Optics PHYS 1110L Conceptual Physics Lab Date: -(10 pts max) INTRODUCTION When you hold your glasses far away from your face, what do you see? If you look through a magnifying glass and move it away from your face, something odd happens as you look through the moving lens. The light that reflects off images and passes through a lens before it arrives at your eye can be simulated as a series of rays. In this lab, you will investigate lens optics using the 3-ray system (parallel-focal, focal-parallel, central). Remember, the real focal point of a lens is behind the lens. The lens we will use in this simulation is a thin double-convex lens orta Please note that in some texts, the object's distance is given by "p and the image's by "q Table 1. Variable Identification Please take some time to define the each of the variables present in the above equations: Variable Units do di ha ho 1 of 1
