The term 'light-bending device' can be summarized as a PRISM, which is a five-letter word. A PRISM is an optical device that is used to refract light and create a spectrum of colors. It is made up of two or more triangular glass surfaces that are joined together at their edges. Prisms are commonly used in optics, photography, and laser applications. They are also used to create rainbows and other colorful displays.
