The document describes image formation using curved mirrors through ray diagrams. It shows that when the object is outside the center of curvature, the image is smaller, inverted, and real; when the object is between the focus and center of curvature, the image is bigger, inverted, and real; and when the object is at the focus, no image is formed. It also demonstrates that the image is always bigger, upright, and virtual when the object is between the focus and mirror.
