Web1.3 Ray Tracing Rules for Thin Lenses Following what we did for mirrors, we will first discuss the ray tracing rules for thin lenses (see Figure 5 on Page 8). • The first ray (i.e., Ray 1) is drawn parallel to the optical axis from the top of the object. After being refracted by the lens, this ray either passes through the focal point, F, on WebSee, what u r talking about is called 'sign convention'.....where u assume a Cartesian plane in which the optical centre of the lens acts as the origin and the principal axis as the x-axis.....so any distance on the left side of lens is taken as negative (u= do= distance of the object from the lens) and any distance on the right is taken as positive(v= di= distance of …

WebA thin lens is one whose thickness is small compared to the other characteristic distances (e.g., its focal length). The surfaces of the lens can be either convex or concave, or one surface could be planar. Because of the refractive properties of its surfaces, the lens will either converge or diverge rays that pass through it.
