SSC MTS EXAM

Detailed explanation-1: -As the object is moved away from a convex mirror, the distance of virtual image (formed behind the mirror) from the mirror increases (between pole and focus), the image shifts from the pole towards the focus and the size of the image gradually decreases. When the object is at infinity, the image is at its focus.

Detailed explanation-2: -As the pencil is moved away from the mirror, the image becomes smaller. When the object is moved away from the mirror, the image would move closer to the focus of the mirror.

Detailed explanation-3: -Solution: In case of a convex mirror, as the object moves from infinity to the pole of the mirror, the virtual image moves from its focus to the pole of the mirror.

Detailed explanation-4: -The image formed by a convex mirror is always erect, virtual and diminished irrespective of the position of the object. Whereas a concave mirror can form both real and virtual images depending upon the position of the object with respect to the mirror.
