The linear magnification produced by a spherical mirror is +1/3.Analysing this value state
a. Type of mirror and
b.Postion of the object with respect to the pole of the mirror.
Draw ray diagram to justify your answer.

a) Magnification is positive, so it is an erect image. Furthermore, The object is bigger than the image, so the mirror is a convex mirror.
b) Wherever the object is placed in front of a  convex mirror, a virtual and erect image will be formed.
