The term REFRACTION DEVICE can be summarized as a device that uses a PRISM to bend light. A PRISM is a transparent optical element with flat, polished surfaces that refracts light. It is typically made from glass or plastic and is used to separate white light into its component colors. Prisms are commonly used in optical instruments such as telescopes, microscopes, and cameras. They are also used in scientific experiments to study the properties of light.
