By the end
- 01Locate the focal points of thin converging and diverging lenses
- 02Find image position, size, orientation, and type with principal-ray diagrams and the thin-lens equation
- 03Apply the sign convention for real and virtual images and for converging and diverging lenses
- 04Compute magnification and predict how the image changes as the object moves
