Thin Converging Lens 3rd ray for ray tracing?? Lens Equation Lateral Magnification Sign Rules • Object distance: on the same side as the incoming light, POSITIVE • Image distance: on the same side as the outgoing light, POSITIVE • Converging lens: POSITIVE focal length • Height: Above the principal axis, POSTIVE Virtual Image • When the outgoing principal rays to NOT converge at a point (the real image), then extend the rays backward to find the virtual image. Angular Magnification M = Θimage’ / Θobject
