🧠 Memory Aid
Convex vs Concave: Con-VEX = VEXed, it pushes rays inward (converges). Con-CAVE = CAVEd in, it pulls rays outward (diverges).
Real vs Virtual image: REAL rays Really meet. VIRTUAL rays only Virtually (seem to) meet.
Object position → image type (convex lens):
- Object beyond 2F → real, inverted, diminished
- Object at 2F → real, inverted, same size
- Object between F and 2F → real, inverted, magnified
- Object closer than F → virtual, upright, magnified (magnifying glass!)
