If an object is placed at a distance of 9 cm from a concave mirror of focal length 10 cm then which type of image will be formed?

Q.

Name the kind of mirror used to obtain

(a) a real and enlarged image,

(b) a virtual and enlarged image,

(c) a real and diminished image, and

(d) a virtual and diminished image.

Q.

A concave lens forms the image of an object which is :

(a) virtual, inverted, and diminished

(b) virtual, upright, and diminished

(c) virtual, inverted, and enlarged

(d) virtual, upright, and enlarged.

Q.

For the object placed between the optical centre and focus of a convex lens, the image is :

(a) real and enlarged

(b) real and diminished

(c) virtual and enlarged

(d) virtual and diminished.

Q.

An object is placed at the following distances from a concave mirror of focal length 15 cm, turn by turn : (a) 35 cm (b) 30 cm (c) 20 cm (d) 10 cm Which position of the object will produce : (i) a magnified real image ? (ii) a magnified virtual image ? (iii) a diminished real image ? (iv) an image of same size as the object ?

Q. Use the mirror equation to deduce that:

A) An object placed between f and 2f of a concave mirror produces a real image beyond 2f.

B) A convex mirror always produces a virtual image independent of the location of the object.

C) The virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole.

D) An object placed between the pole and focus of a concave mirror produces a virtual and enlarged image.
