A convex lens of focal length 10 cm is painted black at the middle portion as shown in figure. An object placed at a distance of 20 cm from the lens. Then

A

only one image will be formed by the lens

B

the distance between the two images formed by such a lens is 6mm

C

the distance between the images is 4mm

D

the distance between the images is 2mm

Text Solution

Verified by Experts

The correct Answer is:
a.

Only one image will be formed by this lens system because optic axis of both the parts coincide. Two images would have formed if their optic axis were different.

In an experiment for the determination of focal length of the convex mirror a convex lens of focal length 20cm is placed on the optical bench and an object pin is placed at a distance 30cm from the lens. When a convex mirror is introduced in between the lens and the real and inverted image of the object, the final image of object O is formed at O itself. If the distance between the lens and the mirror is 10cm, then the focal length of the mirror is

A point object is placed at a distance of 12 cm from a convex lens of focal length 10 cm.
