Designed to study and demonstrate Snell's Law of Refraction.

• Made with high quality acrylic plates
• Edges and points are fully cemented
• Includes stopper for leak-free use when filled

When referring to light or other waves passing through a boundary between two different isotropic media, Snell's law can be used to describe the relationship between the angles of incidence and refraction. Fill the hollow cube with a liquid of your choice. These are also useful when studying other principles of light manipulation, light rays, and light angles.
