Experiment 5: Thin lenses
Ray Diagram for thin lenses
Locations of Object u and Focal point F are draggable; so are the handles of the green measuring bars.
Lens is a converging lens for f > 0, diverging lens for f < 0.
Light always travels from left to right in this applet, regardless of position of object. Object is virtual if placed to right of lens.
u = object
v = image
ho= height of object
hi=height of image
