The Attempt at a Solution


My guess is that either L or Fo are negative, but a negative magnification makes no sense, so basically it is a substitute for a modulus. Note: negative magnification could not possibly mean the image is diminished, because a diminished image simply has a magnification of less than 1 but greater than 0.

It may be because of the sign convention. Here the object and image are in the opposite direction of the axis.

I don't believe either measurement qualifies as virtual
