A Simple Microscope

Construction:
Both the objective lens and the eyepiece lens are converging lenses.
Use three colors to carefully construct the rays that form the final image for the object given.
Carefully label the first image as I
_{1}
and the final image as I
_{2}
.
Measurements and Analysis:
Measure the height of each image, I
_{1}
and I
_{2}
, as well as the original object, O.
Measure d
_{i}
and d
_{o}
for each individual lens.
Calculate the final magnifications for the lens system using the following ratios:
M
_{1}
= M
_{microscope}
=  I
_{2}
/ O 
M
_{2}
= M
_{microscope}
= (M
_{objective lens}
)(M
_{eyepiece lens}
) where M
_{lens}
=  d
_{i}
/ d
_{o}
