Answer:
The object is placed at the center of curvature.
Explanation:
When a hollow spherical is cut into parts and the outer surface of each cut portion is painted, it forms a mirror, with the interior surface reflecting. This sort of mirror referred to as a concave mirror.
Characteristics of Concave Mirrors
- When light hits the concave mirror's reflecting surface, it converges at a single point and reflects back. This is why it is sometimes referred to as a converging mirror.
- When the concave mirror is put very close to the object, a magnified, erect, and virtual picture is obtained.
- The size of the image, however, decreases as the distance between the object and the mirror increases, creating a real and inverted image instead.
- The concave mirror can produce a small or large, real or virtual image.
Image formation by concave mirror when the object is placed at the center of curvature:
When an object is positioned at the center of curvature, an image of the same size as the object is also formed at the center of curvature. In this instance, the image will be real & inverted (i.e., a right-side-up object results in an upside-down image).
