They are widely used in physics and chemistry classes to demonstrate how light bends when passing through different materials. A triangular prism is a three-sided geometric shape with two triangular bases and three rectangular faces. When light passes through a triangular prism, it refracts, or bends, due to the change in speed as it moves from one medium to another. This phenomenon is the basis for understanding how rainbows form and how lenses work. In educational settings, triangular prism items are used to help students visualize and understand the behavior of light. They are particularly useful in teaching the concept of dispersion, where white light is separated into its component colors.
