Image Hunt

This is an interactive science lesson that uses the lens simulation to explore images created by a converging or convex lens. The simulation was created by the Physics Education Technology Team (PhET) at the University of Colorado.

Lenses are everywhere! We find them in our eyes, in cameras, and in a rain drop. We create images by simply opening our eyes. The human eye can be classified as a compound lens and the eye muscles contract or expand to change the focal length of this compound lens. By changing the focal length of our eye we insure that an image is formed at the optic nerve so the information can be transmitted to our brain for processing. Are you interested in how your eyes work? How about cameras, microscopes, and telescopes?

Follow me to where it all starts!
