Based on the ray diagrams shown in Figure (a) and (b), what can be concluded about the image formation by a convex mirror for an object at infinity and a finite distance, respectively?

Without the specific details of Figure (a) and (b), I’ll provide a general explanation based on common ray diagrams for convex mirrors.

For an object at infinity (Figure a): The rays parallel to the principal axis after reflection appear to diverge from the focal point behind the mirror. The image is virtual, diminished, and formed at the focal point.

For an object at a finite distance (Figure b): The rays parallel to the principal axis reflect as if they originated from the focal point. The image is virtual, erect, and formed between the focal point and the mirror, resulting in a magnified appearance.
