Prisms

A prism is a transparent optical element that refracts, or bends, light. It usually has two flat surfaces and a triangular shape. When light enters a prism, it slows down and changes direction based on the prism's angle and the light's wavelength. This bending separates light into its component colors, creating a spectrum, like a rainbow. Prisms are commonly used in optics for applications such as correcting lenses, producing visual effects, and guiding light in devices like cameras and telescopes. Their ability to manipulate light makes them essential in various scientific and practical contexts.
