What 2 factors can determine the type of image formed by a lens?

The two primary factors that determine the type of image formed by a lens are the position of the object relative to the lens's focal point and the curvature of the lens itself. When an object is placed beyond the focal point, a real, inverted image is formed; when it is placed between the focal point and the lens, a virtual, upright image is produced. Additionally, the lens's curvature affects its focal length, influencing how light rays converge or diverge, thereby impacting the image characteristics.
