Spark your students' interest in light and optics with an exciting demonstration of the law of reflection. The Infinity Mirror features two parallel mirrors and a circle of small white bulbs that, together, produce what appears to be an endless number of lights that stretch to infinity. It takes the normally mundane topic of the physics of plane mirrors- something that students have all seen, every morning before they come to school and presents it in a new and fascinating way. Just turn it on and the "Wow... that's cool!" and "How does it work?" comments will soon follow.
Once you've grabbed their attention, you can move onto other critical thinking activities such as finding virtual images in plane mirrors, understanding the inner workings of a periscope, or learning how a car rear-view mirror's day/night feature works.
To demonstrate how the Infinity Mirror works, have your students arrange two plane mirrors at right angles to each other. Place a colored pin between them and challenge your students to count the number of virtual images that are formed. Then repeat the experiment at 72°, 60°, 45°, and 30° angles. Seeing how the number of images formed increases as the angle decreases will give your students a solid understanding of how the Infinity Mirror produces it amazing effect... to infinity and beyond!
The Infinity Mirror measures 12" X 14"L. Operates on 110 volts AC. Two replacement bulbs included.
