A converging lens is a convex lens that converges light. This means that the converging lens causes parallel light rays to come together. The point at which the parallel rays of light meet is called the focal point. Such lenses create real images. In optics, a real image is an image that is formed by converging light rays.

A converging lens is a convex lens that converges light. This means that the converging lens causes parallel light rays to come together. The point at which the parallel rays of light meet is called the focal point. Such lenses create real images. In optics, a real image is an image that is formed by converging light rays. The real image is found in the plane of convergence. When a screen is placed within this plane, then the real image can be seen on the screen. Thus, the images found on the screens in movie theaters are examples of real images.
On the other hand, a diverging lens is a concave lens that causes light rays to refract and diverge. Such lenses form virtual images.
