Calculate focal length, object distance, image distance, and magnification
📐 Thin Lens Formulas
1/f = 1/do + 1/di
M = -di/do = hi/ho
Power = 1/f (in diopters)
f = focal length, do = object distance, di = image distance, M = magnification

💡 Tips & Information
- Positive focal length = converging lens, negative = diverging
- Real images form on opposite side of lens from object
- Virtual images form on same side as object
- Magnification > 1 = enlarged, < 1 = reduced
- Power in diopters = 100/focal length (cm)
