SUMMARY
A converging lens with a focal length of 0.246 m creates a virtual image located 0.933 m from the lens on the same side as the object. The correct formula to use for this scenario is 1/f = -1/di + 1/do, where di is the image distance and do is the object distance. The calculated object distance is do = 0.197157 m, which is incorrect due to a misapplication of the lens formula. The correct approach requires careful attention to the signs of the distances involved.
