This resource is a lesson aimed at teaching Physics: Waves. This lesson looks at how concave lenses work, and how we use them in the real world.
This lesson has 4 learning objectives that are structured in the IDEAL format:
*Describe the main differences between a convex and a concave lens.
*Explain, using ray diagrams, how images are formed using concave lenses.
*Apply calculation to find the magnification of an image using a lens.
*Link your understanding of lenses to draw ray diagrams to explain how Galileo's telescope worked.
This lesson is designed with challenge questions throughout to stretch your most able students, aimed at getting the most out of the more able students.
Review the lesson before teaching to see how the animations will work in your lesson.
