A microscope is a device where a first lens makes a real image of an object, and that real image is then viewed with a second lens used as a magnifying glass to make a virtual image that is enlarged.

The picture shows the two converging lenses of a compound microscope: the objective lens (on the left) near which the object to be viewed is placed, and the eyepiece lens (on the right) which functions as the magnifying glass. The objective lens has a focal length fobj (with focal points indicated by an "x"), the eyepiece lens has a focal length feye (with focal points indicated by an "o"), and the two lenses are separated by a distance L. The picture may not be to scale, but it will at least allow you to correctly determine the kinds of images formed by each lens.

F. What is the magnification due to each individual lens?
mobj = ______
meye = ______

G. The total magnification is the product of the magnification due to each individual lens, and it is the ratio of the final image height over the original object height. If you are viewing a cell with a size of 10 μm, what is the size (absolute value) of the image that you view by looking through the eyepiece?
size =  _____ μm
