Refraction is the bending of light when it passes from one medium to another, such as from air into glass or water. This happens because light changes speed in different materials. A convex lens uses refraction to bend incoming rays toward a focal point, forming images. The effect allows cameras, microscopes, telescopes, and even the human eye to focus light and produce clear vision. Want more interesting content like this ?
