Equilateral Glass Prism 25mm/75mm

Equilateral Glass Prism 25mm/75mm for Optics Experiments

A large glass prism with 60° angles, an equilateral cross-section with 25 mm sides, and a length (height) of 75 mm. Ideal for conducting physics experiments in optics, including but not limited to the standard classroom demonstration of light dispersion. Using prisms you can study the refraction of light (a light ray) in the prism and in other media, total internal reflection, and determine the critical angle.
