Which mirror is used as rear view mirror in vehicles

The correct answer is Convex.

Key Points

• Convex mirrors are used in vehicles as rear-view mirrors.
• They provide a wider field of view, allowing drivers to see more of the area behind and to the sides of the vehicle.
• Convex mirrors form virtual, erect, and diminished images, which help in better judgment of distance and speed of vehicles approaching from behind.
• Due to their curved outward surface, convex mirrors minimize blind spots and enhance road safety.

Additional Information

• Concave Mirrors: Concave mirrors form real, inverted images when objects are placed beyond the focal point. However, when objects are near the mirror, they form virtual, erect, and magnified images. These mirrors are not suitable for rear-view mirrors as they provide a limited field of view and distort the perception of distance.
• Plane Mirrors: Plane mirrors produce virtual, erect, and same-size images. While they can provide accurate reflections, their field of view is limited compared to convex mirrors, making them less effective as rear-view mirrors in vehicles.
