Hollow Glass Prism with Stopper, 2 x 2 x 2"

This Eisco Labs Hollow Glass Prism measures 50×50×50mm (2×2×2") and is constructed from glass plates carefully cemented together. The hollow interior can be filled with various liquids, enabling a wide range of optics experiments including the study of Snell’s Law of Refraction and dispersion phenomena. A stopper is included to seal the cube during use. Filling the prism with different liquids allows students to observe how the index of refraction changes with the medium, making this an engaging, hands-on tool for physics classrooms. The transparent glass construction provides clear visibility of light behavior as it passes through the cube.
