Case1:- When an object is placed anywhere between pole (P) and infinity in front of a concave mirror.
the image formed between
1:-behind the mirror between P and focus F
2:-Virtual and erect
3:-Diminished(smaller than the object)
Example:-the image of matchstick in the convex mirror is virtual erect and diminished(smaller in size)
Case2;-When the object is at infinity
the image formed between
1:-Behind the mirror at focus F
2:-Virtual and erect
3:-Highly diminished (smaller than the object)
Note:-We do not use concave mirror in motor vehicle as a rear -view because its image formation is real and inverted.so all vehicles become upside of plane type become up and body become downside.

Use of convex mirror
1:-Convex mirror are used as rear -view mirror in vehicle(like car ,truck) to see the traffic at the rear side or back sideNote:-We do not use concave mirror in motor vehicle as a rear -view because its image formation is real and inverted.so all vehicles become upside of plane type become up and body become downside.
