6.4 — Images Formed from Lenses
Lenses shape light by refraction — bending rays so images can be focused, enlarged, or projected.

🧭 Plot Summary
Lenses form images by refraction. Unlike mirrors, lenses bend light as it passes through them, causing rays to converge (come together) or diverge (spread apart).
In this lesson, you’ll use the ray model to predict where an image forms, whether it’s real or virtual, and how the image size changes when the object moves. The goal is conceptual mastery: tracing a few key rays and making solid predictions.
Why it matters:
Lenses power cameras, projectors, microscopes, telescopes, and your own eyes. If you understand lens image formation, you can explain how focusing works and why optical devices magnify.
Inside: detailed explanations, graphical relationships, mathematical reasoning, and guided practice.
