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

only one image will be formed by the lens

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

the distance between the images is 4mm

the distance between the images is 2mm

Text Solution

Verified by Experts

The correct Answer is:

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.
