hello..
Because the image is smaller, more image can fit onto the mirror, so a convex mirrorprovides for a larger field of view than a plane mirror. This is why they are useful. They are used whenever a mirror with a large field of view is needed. For example, the passenger-side rear view mirror on a car is convex.
