1 Images in Lenses

2 How to Locate the Image in a Converging Lens
A ray parallel to the principal axis is refracted through the principal focus (F)

3 How to Locate the Image in a Converging Lens
2. A ray through the secondary principal focus (F’) is refracted parallel to the principal axis.

4 Images in Converging Lenses

5 Images in Converging Lenses

6 Images in Converging Lenses

7 Images in Converging Lenses

8 How to Locate the Image in a Diverging Lens
A ray parallel to the principal axis is refracted as if it had come through the principal focus (F)

9 How to Locate the Image in a Diverging Lens
2. A ray that appears to pass through the secondary principal focus (F’) is refracted parallel to the principal axis
