A real image of an object is to be obtained. The mirror required for this purpose is : (a) convex (b) concave (c) plane (d) either convex or concave

Q.

A real and enlarged image can be obtained by using a :

(a) convex mirror

(b) plane mirror

(c) concave mirror

(d) either convex or plane mirror.

Q. A real image, equal in size to the object, is obtained when the object is placed at the centre of curvature in front of
(a) a plane mirror.
(b) a convex mirror.
(c) a concave mirror.
(d) either a convex or a concave mirror.

Q.

Question 4

You are provided with a concave mirror, a convex mirror, a concave lens and a convex lens. To obtain an enlarged image of an object you can use either

(a) concave mirror or convex mirror.

(b) concave mirror or convex lens.

(c) concave mirror or concave lens.

(d) concave lens or convex lens.

Q.

No matter how far you stand from a mirror, your image appears erect. The mirror is likely to be

(a) plane

(b) concave

(c) convex

(d) either plane or convex

Q.

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
