Answer 2

Rear-view and side-view mirrors of vehicles are convex mirrors. 

They form erect, virtual, and diminished images which allow the driver to view a large area in a small mirror. Similarly, safety mirrors fixed in stores can form images of a number of visitors at a time, which helps the store staff to monitor their activities.
