An object is placed in front of a convex mirror. Which one of the following statements is correct?
Explanation
A convex mirror is a diverging mirror that always forms a virtual, erect, and diminished image of a real object, regardless of the object's position [3]. Because the image is always erect, it will never form an inverted image [3]. According to the mirror formula and ray diagrams, as an object moves closer to the mirror, the image moves from the focus towards the pole, not towards the focus [2]. Furthermore, the magnification of a convex mirror is always less than one, meaning the image is always smaller than the object; thus, it cannot be enlarged even if placed at half the focal length [3]. Since the reflected rays only appear to originate from a point behind the mirror, the image is strictly virtual and cannot be real or inverted [3].
