convex mirror
The mirror in this case is a convex mirror, as virtual images are formed by convex mirrors.
it is a convex mirror as it produces diverging waves
since the convex mirror is curved outwards the the focus is behind the mirror

convex
The image formed by the convex mirror is virtual, erect and diminished.
A concave mirror curves inward in the middle, while a convex mirror curves outward in the middle.
A convex mirror forms a virtual, upright, and diminished image of the object placed in front of it. The image is also located behind the mirror.
concave and convex mirror
There is a plane mirror on the driver's side and a convex mirror on the passenger's side. The reason only the passenger mirror is convex is because you are farther away from it. The angular view provided by farther mirror of the same physical size produces a similarly smaller reflected field of view. The convex mirror provides a larger field of view- one that should be comparable to the closer drivers mirror.
