The Compound Microscope

  1. Mar 5, 2010 #1
    1. The problem statement, all variables and given/known data
    At this site http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/micros.html , what does the negative sign indicate in the Mo formula?


    2. Relevant equations
    On website


    3. 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
