Question

why are Mirrors fitted on the outside of cars convex

Answer 1

Because the image is smaller, more image can fit onto the mirror, so a convex mirror provides 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.

Answer 2

This is because a convex mirror forms a highly-diminished image, thus making the traffic look much smaller. As a result, we can see a large number of vehicles in a very small
mirror.
