I 4 Lab 14: Ray tracing & image formation Differentiate between Real and Virtual images. Understand how image formation occurs using concave and convex lenses. Understand how image formation occurs using concave and convex mirrors. Draw the geometrically accurate trajectory of light through convex and concave lenses in various arrangements. Draw the geometrically accurate trajectory of light reflected by convex and con- cave mirrors. Apply the correct mathematical model to arrangements of mirrors and/ or lenses. Calculate the size (height) and location (focal point) of images produced by ware ious arrangements of mirrors and lenses. 14. 1 principal rays Click this Geometric optics simulation link, then the \"Play" icony and select "lenses,\" check the "principal\" box, and select the arrow image in the dropdown box at the top left. Principal rays are the rays which are used to derive the mathematical relations, due to their easily observable geometric properties. In table 141 observe how the trajectory of each ray is aected by the lens. Categorize each Refracted ray as either unchanged, parallel to axis, or intersecting image focus. Incident Ray trajectory Refracted Ray Trajectory Ray 1: parallel to axis Ray 2:1ntersecting object focus Ray 3: Ray Incident on center of lens Table 14.1: Analysis of principal Rays Page 4 of 4 CHAPTER 14.
