WebCombination of thin lenses Consider two thin convex lenses L 1 and L 2 of focal length f 1 and f 2 placed coaxially in contact to each other. A point object O is placed in the principal axis at a distance u from the lens L 1.In the absence of lens L2, as the rays of light incident on the lens L 1, this lens L 1 converges the rays, and thus, image is formed at point I 1. Web3.2.6 Thin Lenses Download PDF Test Yourself Features of Lens Diagrams Lens diagrams can be described using the following terms: Principal axis Principal focus, or focal point Focal length The principal axis is defined as: A line which passes through the centre of a lens The principle focus, or focal point, is defined as:

This topic will be discussed in the next part of Lesson 5. For now, internalize the meaning of the rules and be prepared to use them.
Webthe surfaces. These are called “thin” lenses. One defines focal points for lenses in a way similar to that for mirrors. If, after passing through the lens, incident rays parallel to the axis are converged at a point, then that point is the focal point, and we have a converging or positive lens; its focal length (the WebDownload all Secondary Chemistry Teaching/Learning Resources, Notes, Schemes of Work, Lesson Plans, PowerPoint Slides, & Examination Papers e.t.c.
