Object and its image always move along the normal with respect to the mirror in opposite directions.

(A) For all types of mirrors (i.e.,plane mirror,convex mirror,and concave mirror),the object and its image always move along the normal with respect to the mirror in opposite directions. This is a fundamental property derived from the mirror formula and the magnification relation. As the object approaches the mirror,the image also approaches the mirror from the opposite side,ensuring their relative velocities along the normal are always in opposite directions.

Velocity in Mirrors (Kinematics)

$A$ plane mirror is placed along the $x$-axis facing the negative $y$-axis. The mirror is fixed. $A$ point object is moving with a velocity of $3\hat{i} + 4\hat{j}$ in front of the plane mirror. Find the relative velocity of the image with respect to the object.
