Solution
Convex mirror
It's a curved mirror with a reflective surface that bulges out towards the source of light.
Characteristics:
Because light rays diverge as they strike a convex mirror's reflecting surface, it is also known as a diverging mirror.
Convex mirrors always produce virtual, erect, and reduced pictures, regardless of the distance between the item and the mirror.
Image formation by convex mirror:
When an object is placed at infinity.
We assume two rays parallel to the principal axis and one directed towards the pole of the mirror originating from the object for image formation by a convex mirror in this condition.
These mirrors diverge the rays so the rays get converged virtually at focus behind the mirror.
Hence, the resulting image is a very diminished, virtual, and erect image.
When the object is placed between infinity and pole
We consider two separate rays originating from the object in this circumstance of image generation via a convex mirror. These mirrors diverge the rays so the rays get converged virtually.
One travels parallel to the main axis, while the other is aimed at the mirror's center of curvature.
These rays form an image between the pole (P) and the focus (F) behind the mirror after reflection.
The result is a diminished, virtual, and erect image.
Hence, the size of the image formed by the convex mirror is always smaller than the size of the object irrespective of the position of the object.
