Five different acrylic shapes let you study the behavior of one or several rays as they pass through solid objects. Each shape has a matte supporting surface that lets students look from above to see the light beams inside the lens. The shapes include a trapezoid, a right-angle prism, a semicircular lens, and convex and concave lenses. Students can also examine light ray paths in liquids with the two hollow acrylic cells (rectangular and semicircular). A universal plastic mirror combines plane, concave, and convex mirrors with focal lengths of 60mm on each curved side.
