What happens to the size of the image as the viewer moves further away from a concave mirror after being close to it?

When a viewer moves further away from a concave mirror, the size of the image undergoes specific changes based on the position of the viewer relative to the mirror. Initially, when the viewer is close to the concave mirror and within its focal length, the image produced is virtual, upright, and larger than the object. As the viewer increases the distance from the mirror, eventually they will cross the focal point.

Once the viewer is beyond the focal length, the concave mirror starts producing real images that are inverted and smaller than the actual object. Specifically, as the viewer continues to move further away from the mirror, the size of the image decreases, and it flips upside-down. This characteristic behavior of concave mirrors is a result of the way they reflect light rays, which converge to form an image at different distances.

Therefore, the image getting smaller and flipping upside-down as the viewer moves away accurately describes the behavior of images formed by concave mirrors beyond their focal point.
