1. Properties of lenses

2. Learning goals We are learning to the types of lenses.
We are learning to find images in lenses.

3. 1. Converging lenses Lens that is thickest in middle
Causes light rays that are parallel to PA to converge, or meet at one point called the principal focus (F)

4. 2. Diverging lens Thinnest in middle
Causes parallel light rays to diverge, or spread apart

6. Emergent ray
light ray that leaves lens after refraction
