| Klinger Blackboard OpticsT is a unique approach to teaching principles of optics and properties of light. Experiments in refraction and reflection are performed directly on the blackboard without darkening the room. Visibility is assured because of the large acrylic lenses. The special ray projectors may be arranged to form a pencil beam of light or a divergent cone by means of a fingertip adjustment. With the components in place, the instructor can chalk in axes, normals, tangents and equations directly on the chalkboard. |

| Experiments Include: The laws of reflection; virtual image with a plane mirror, convex mirror, and a concave lens; focal length of concave and convex mirrors; focal length of Planoconvex and Planoconcave lenses; real image formed by a concave mirror; simple refraction; less dense to more dense medium; parallel displacement by a rectangular block; semicircular body, light incident at center if disc, and at right angles to tangent, critical angle; total internal reflection, reversing prism. |
