Light-refracting devices are objects that bend and disperse light, such as prisms. Prisms are six-sided polyhedrons with two triangular faces that meet at an edge, allowing light to pass through and refract in different directions. Prisms are often used in optical instruments, such as telescopes, microscopes, and binoculars, to help focus and magnify light. They are also used in decorative lighting fixtures and in scientific experiments.
