Answer 2

Prefer a convex mirror as a rear view in vehicles:

• We prefer a convex mirror as arear view mirror in vehicles because it gives a wider field of view, which allows the driver to see most of the traffic behind him.
• Convex mirrors always form a virtual, erect, and diminished image of the objects placed in front of it.
• The image produced by a convex mirror is always virtual and located behind the mirror.
• When the objects is far away from the mirror, the image is upright and located at the focal point.
• As the object approaches the mirror, the image also approaches the mirror and grows until its height equals that of the objects.
• The image formed by convex mirrors are smaller than the object but gets larger as they approach the mirror.
