Object Image and Focal Distance Relationship (Proof of Formula)

In addition to the image distance, another characteristic feature of a lens is the relation between the size of the image and the size of the object. This is called the magnification of the lens, and it also depends on the object distance.

The next two videos are optional information for those of you who would like to understand how to get the formulas in the text by analyzing the geometry of the ray diagrams.
