The image of the object moves slower compared to the object. It can be explained using the mirror formula :u1​+v1​=f1​ We know that for a convex mirror, the object distance ( u ) is positive, image distance (v) is negative and the focal length (f) is also negative. Thus mirror formula of a convex mirror is:u1​−v1​=−f1​As u=+ve​v1​−f1​>0v1​>f1​v
