Diverging Lens

Overview

A diverging lens will produce a virtual image, no light actually focuses to the image position. This virtual image can not be projected onto a screen and would not expose film since no light is actually at the image position. Virtual images are very common such as the image in a flat mirror.

Double Concave lens

• On your desk is a double concave lens.
• Try to determine the image position for some object at several nearby distances. (This is not easy to do, you will probably only be able to make a rough estimate of where the image is)
• Draw a sketch in your notebook of the lens showing your view and the apparent image of a nearby object.
• Describe some experiment that could be done to more accurately determine the image position
