The term 'light reflector' can be summarized as a PRISM, which is a five-letter word. A PRISM is a transparent optical element with flat, polished surfaces that refract light. It is often used to break up white light into its component colors, creating a rainbow effect. Prisms are also used in optics to reflect and disperse light, making them useful for a variety of applications such as microscopy, telescopes, and lasers.
