What is the behavior of light that causes msgnifying glasses and contact lenses to bend light rays?
The behavior of light that causes magnifying glasses and contact lenses to bend light rays is called refraction. When light passes from one medium (such as air) to another (such as glass or plastic), its speed changes, causing it to bend. This bending of light is what allows magnifying glasses and contact lenses to focus light and improve vision.
