A virtual image produced by a lens is always?
Answer D is correct.





You can verify with a magnifying lens.





When a magnifying lens is used to view objects enlarged, the virtual image is formed at the back of the lens





A and B are partially correct and C is wrong. D is fully correct.
Reply:c. located in front of the lens





that is it is formed on the same side as the object.
Reply:D. Located in the back of the lens, i.e. on the same side as the object. This is true for both convex and concave lenses. In the case of the convex lens, the virtual image is always larger but in the case of the concave lens, the virtual image is always smaller. Since you did not specify what type of lens, the answer is D.
