rainbow: A rainbow is formed when sunlight refracts in water droplets in the atmosphere. White light is decomposed into its component colors due to refraction at different angles. Prisms: A glass or crystal prism can decompose white light into a spectrum of colors. When passing through the prism, light refracts and disperses into the colors of the rainbow. Optical Lenses: In glasses or camera lenses, refraction is used to focus light on a specific point. The shape of the lens (convex or concave) affects how light refracts to correct vision problems or focus images. water mirrors: On hot days, the hot air near the ground can cause light to refract, creating the illusion of water on the horizon (a phenomenon called "Mirages").
