Which type of mirror is commonly used as a rear-view mirror in vehicles because it provides an erect and diminished image with a wider field of view?

💡 Solution & Explanation

Convex mirrors are universally preferred as vehicle rear-view mirrors because they diverge incoming light rays to produce virtual, erect, and diminished images, thereby providing a much wider field of view of traffic behind. Concave mirrors form inverted and magnified images which are unsuitable for driving observations. Plane mirrors offer limited field coverage without diminishing the reflection size.
