Light source in metal housing on magnetic foil for experiments demonstrating ray optics on a whiteboard. Experiments on reflection, refraction, and basic lens laws can be performed using five narrow light rays emerging from the right-side. With the help of rotating mirrors, these rays can be directed to make parallel, divergent, or convergent beams; the beams can be masked out individually. Demonstrations on shadow casting can be conducted using the two divergent light rays emerging from the left-hand side. With the help of rotating mirrors, these rays can be directed or masked out individually.
