Use the mirror equation to deduce that: the virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole.
For a convex mirror, the focal length (f) is positive When the object is placed on the left side of the mirror, the object distance (u) is negative For image distance v, we have the mirror formula v1+u1=f1 v1=f1−u1 but u<0 therefore v1>f1 v<f Hence, the image formed is diminished and is located between the focus (f) and the pole
