A convex mirror consistently forms images that are virtual, erect, and diminished. These images are always located between the pole (P) and the principal focus (F) of the mirror.
Initial Position: When the object is at infinity, the image is formed exactly at the principal focus (F). This image is virtual and highly diminished.
Movement Scenario: As the object starts moving slowly from infinity towards the pole (P), the image undergoes a corresponding movement.
Therefore, as the object moves from infinity towards the pole of a convex mirror, the image moves from the principal focus (F) towards the pole (P).
