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.
