The magnification produced by a mirror is +1/3. Then the mirror is a _______ (concave mirror, convex mirror, plane mirror)

The magnification produced by a mirror is +1/3. Then the mirror is a convex (concave mirror, convex mirror, plane mirror)


Explanation: The magnification of a mirror is given by



Where v is the image distance and u is the object distance.


The magnification can only be positive if the object and the image are on the opposite sides of the mirror, which is achieved only when we use a convex mirror.
