उत्तर
When an object is kept within the focus of a concave mirror, an enlarged image is formed behind the mirror. This image is virtual and erect.
Explanation:
When an object is in the focus of a concave mirror (between the pole and the major focus), the light rays reflecting off it diverge. Because these rays do not intersect in front of the mirror, they appear to come from a location behind it when extended backward. This creates a virtual image that cannot be captured on screen. Such an image is always erect (upright) and larger (magnified) than the object.
