Cenco Physics Rive Ray Box
High quality and low cost make this easy-to-use ray box ideally suited for junior high or high school students
It is durably constructed with a rigid vinyl base and a metal box housing a transformer and a high intensity light. An adjustable screen produces either one wide beam or a choice of one, two, three, or five slit beams, all of which can be easily seen tracing a path across the table surface on which the unit sits
For lenses and mirrors use the Optics Set (68182-01) and the Semi-Circular Lens (68182-02).
The Rive Ray Box operates on 120V, AC and comes with a three-wire cord and plug. CSA listed, with instructions for 15 suggested experiments.
