Type of mirror is convex.
1. Convex mirrors always form images that are virtual, and smaller than the actual object.
2.They are commonly used as rear and side view mirrors in cars and as security mirrors in public buildings because they allow you to see a wider view than flat or concave mirrors.
3.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.
4.They are used whenever a mirror with a large field of view is needed.
