A lens that causes light rays to bend toward (away from) its optical axis is a converging (diverging) lens. By the end of this section, you will be able to use ray diagrams to locate and describe the image formed by a lens and employ the thin-lens equation to describe and locate the image formed by a lens.

P' is now a virtual object point for lens L 2 . To find its image by L 2 , draw ray 4 from P' through the centre of lens L 2 back to S (this ray is refracted by lens L 1 but not by L 2 ) and draw ray 3 as refracted by lens L 2 . Since ray 3 is parallel to the optical axis between the lenses, it passes through the back focal …
