Statement I: Convex mirror is used as a driver mirror. Statement II : Images formed by convex mirror are diminished in size.

Statement I is true as convex mirrors are standardly used as rear-view or driver mirrors in vehicles [1]. Statement II is also true because convex mirrors always produce images that are virtual, erect, and diminished (smaller) in size compared to the object [4]. The diminished nature of the image is the direct reason why Statement I is true; because the images are smaller, the mirror can capture a much wider field of view [1]. This allows the driver to see a significantly larger area of traffic behind the vehicle than would be possible with a plane mirror of the same size [1]. Therefore, Statement II provides the correct scientific explanation for the application described in Statement I, facilitating safer driving by expanding the driver's perspective [3].
