When a plane mirror is displaced a distance $L$ perpendicular to its surface, image point for any fixed object point moves a distance $2L$.

When a plane mirror is displaced a distance $L$ perpendicular to its surface, image point for any fixed object point moves a distance $L$.

When a plane mirror is rotated through an angle $\alpha$ about an axis that lies in the plane of the mirror, the reflected ray for any particular incident ray that is perpendicular to the axis rotates through an angle $2\alpha$.
