In a concave mirror, the size of the image changes as the distance of the object from the mirror increases.
When the object is placed very close to the mirror (closer than the focal length), the image formed is virtual, upright, and magnified. As the object moves slightly away from the mirror, the image becomes larger and moves closer to the mirror.
When the object is placed at the focal point of the concave mirror, the reflected rays become parallel, and the image formed is at infinity.
As the object moves further away from the mirror (beyond the focal point), the image formed becomes real, inverted, and diminished in size. The image continues to get smaller as the object moves farther away from the mirror.
