🎯 Exam Focus
Frequently Examined
This topic is examined in Edexcel 1PH0/1 (Paper 1). Edexcel lens questions often include ray diagram completion, magnification calculations, and explaining how lenses correct long-sight or short-sight — the "describe the image" question type is a reliable Edexcel staple.
Lenses and images typically appear as:
- Ray diagram questions — draw or complete a ray diagram for a convex lens
- Describe the image — state whether it is real/virtual, upright/inverted, magnified/diminished
- Magnification calculations — straightforward formula application
- Vision correction (Higher) — explain how concave or convex lens corrects eyesight
Important: When asked to "describe the image," give ALL three characteristics: real/virtual, upright/inverted, magnified/diminished.
Practice questions for Lenses & Images
What does a convex (converging) lens do to parallel rays of light?
Explain the difference between a converging lens and a diverging lens. Include what each type does to parallel rays of light.
