Name the mirror that (a) can give real as well as virtual image of an object. (b) will always give virtual image of same size of an object. (c) will always give virtual and diminished image of an object. (d) is used by a doctor in examining teeth.

(a) Concave mirrors give real images for all positions of the object between infinity and the focus of the mirror and gives virtual image if the object is between the focus and the pole. (b)The image formed by the plane mirror is of virtual and of the same size as the object. (c) Images formed by convex mirrors are always virtual and diminished for all positions. (d) If the object is placed between the pole and focus of the concave mirror, the image is virtual and erect and highly magnified and hence they are used in examination of teeth by dentists.
