Lenses PowerPoint Presentation

Converging lenses bundle - Presentation & 4 worksheets - GCSE/equivalent

This bundle contains a number of resources to teach the action of converging lenses, as is required by the CIE IGCSE Curriculum & equivalents. The bundle contains 1 presentation & 4 worksheets. The key ideas activity that they cover is using the three lens ray rules to find the locationan and nature of an image given the position of an object in front of a converging lens. Worksheet 1 - a notes worksheet allowing students to annotate the three ray rules. Worksheet 2 - a worksheet allowing students to practice these rules, applying them to cases with different object distances. Worksheet 3 - an example exam-style question, where students need to use the ray rules to find the location and nature of an image. Worksheet 4 - a starter/revision/plenary activity requiring students to link lens terms to their definitions. The presentation covers: * Why we need converging lenses * Converging & Diverging lenses * The action of a converging lens * Converging lens ray rules * Example questions * The different cases of objects placed at different positions in front of a converging lens * The use of a converging lens as a magnifying glass I use these resources as part of the Light topic in IGCSE Physics.
