25.6 Image Formation by Lenses - College Physics 2e - OpenStax
Real images, such as the one considered in the previous example, are formed by converging lenses whenever an object is farther from the lens than its focal length. This is true for movie projectors, cameras, and the eye.
25.6: Image Formation by Lenses - Physics LibreTexts
The table summarizes the three types of images formed by single thin lenses. These are referred to as case 1, 2, and 3 images. Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3).
Robust model for exploring how images are formed by a converging lens. Choose from a variety of object shapes, then view the principal and marginal rays. You can change the lens curvature & diameter and watch what happens to focal length. Move the object to see when the image changes from real to virtual. 4.
Figure 1: Concave lens. 2 Image formation by a convex lens. A convex lens has focal length 100 mm. The lens produces an image from an object is placed 50 cm from the lens. Determine the distance from the lens to the image and the magnification of the image.

How does a lens or mirror form an image? See how light rays are refracted by a lens or reflected by a mirror. Observe how the image changes when you adjust the focal length of the lens, move the object, or move the screen.

When light comes together to form an image, such as on a screen or on the retina (the back of the eye), a real image is formed. Only convex lenses produce real images. A virtual image is formed when light rays are diverging, and so the object appears to be in a different place.
