Lessons in this chapter

  1. 1What Are Spherical Mirrors?Discover how the shape of a reflecting surface changes the mirrors we use.
  2. 2Images Formed by Spherical MirrorsFollow how mirror images change with distance and use those patterns to explain everyday applications.
  3. 3What Are the Laws of Reflection?Investigate the rules that connect an incoming light ray with its reflected path.
  4. 4How Mirrors Converge and Diverge LightSee how curved mirrors gather or spread light and connect this behaviour to solar heating.
  5. 5What Is a Lens, and How Does It Change an Image?Explore curved transparent materials and discover why lenses change the appearance of objects.
  6. 6How Lenses Converge and Diverge LightCompare transmitted light beams and connect lens behaviour to cameras, glasses, and the eye.
  7. 7Chapter Summary and PracticeConnect the whole chapter through a quick recap, comparisons, worked revision, and mixed practice.
