### Description

How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.

### Sample Learning Goals

• Explain how an image is formed by a converging lens using ray diagrams.
• How changing the lens (radius, index and diameter) effects where the image appears and how it looks (magnification, brightness and inversion.
