About This Product
Working on white paper in a dimmed room, students use a single beam to follow reflection from the mirrors and refraction through the rectangular and semicircular blocks, measuring angles to apply Snell’s law. The 3 and 5-beam settings with the convex and concave lenses show rays converging to a focus or spreading apart, which links to real and virtual images and to how the eye focuses.
