Center of Curvature: For a concave mirror, the center of curvature (C) is located at twice the focal length. With a focal length of 5 cm, C is at 10 cm. Object Placement: The object is placed at 10 cm, which is exactly at the center of curvature. Image Formation: When an object is at the center of curvature, the image is also formed at that same point, resulting in a real and inverted image (When the object is located at the center of curvature, the image will also be located at the center of curvature.)(For concave mirror)
