The document discusses how to locate images formed by a convex lens using ray diagrams. It explains that a real, inverted and enlarged image is formed when an object is placed beyond the focal point of the lens. A virtual, erect and enlarged image is formed when an object is placed between the focal point and the optical center of the lens. The document provides examples of ray diagrams to illustrate image formation for objects placed at different distances from the lens.

5. CONCLUCION
• THE IMAGE OF THE OBJECT IN FRONT
OF THE FOCUS IS REAL, INVERTED
AND ENLARGED
• THE IMAGE OF THE OBJECT BETWEEN
FOCUS AND OPTICAL CENTER IS
VIRTUAL, ERECT AND ENLARGED
