Demonstrate how light is bent when it passes through a small hole or through water, and how a flat mirror reflects light. Show how a pinhole camera forms an image without a lens and how light reflects from a roughened surface.
The materials include parts to assemble a variable aperture pinhole viewer, a calibrated optical bench with water cell, a mirror for reflection and refraction experiments, and an optical ray tracer. Complete with five kits, teacher and student copies of assembly and activity guides.
