Spherical Lenses

In this application, you will choose one of two optical tools to make.

This activity is available below or in a printable version.

Create each of the situations below. In doing so, design a lens system for each. Be sure to choose a focal length for your lens and a position for the object. Use a ray diagram to justify your choices. Classify your images by type (real/virtual), orientation (upright/inverted), and size (smaller/same size/larger).

1. A magnifying glass that will help stamp collectors see details on their treasures.
2. A movie projector that will produce an enlarged, real image.
3. A lens that will make a reduced, virtual image for use as a telescope objective.
