Question

At what distance from a convex lens must an object be to get a virtual image?

-at a focal point
-at more than twice the focal length
-greater than the focal length but less than twice the focal length
-at a distance less than the focal length

Answer 1

D, at a distance less than the focal length

Answer 2

The object should be at a distance less than the focal length from the convex (converging) lens in order to get a virtual image. The image formed would be upright, virtual and magnified, just like how a magnifying glass works. The virtual image is produced on the same side of the lens as the object.
