Question
Whatever be the position of the object, the image formed by a mirror is virtual, erect and smaller than the object. The mirror then must be:
(a) plane
(b) concave
(c) convex
(d) either concave or convex
Solution
convex
It should be a convex mirror. This is because when an object is in front of a convex mirror, irrespective of its distance, a virtual, erect and diminished image of the object is obtained.
