What happens to light rays when they pass through a convex lens?

When light rays pass through a convex lens, they converge, meaning they come together to meet at a point after passing through the lens. This is due to the shape of the lens, which is thicker in the middle than at the edges. As light rays enter the lens, they slow down and bend towards the normal, which is an imaginary line perpendicular to the surface at the point of incidence. This bending causes the rays to focus and meet at the focal point on the opposite side of the lens.

By understanding this behavior, it becomes clear that a convex lens is commonly used in applications such as magnifying glasses, cameras, and eyeglasses because it enhances vision by bringing light rays together to form clear images.
