In this problem, we will design a microscope using two convex lenses. The objective lens has a focal length fo = 0.2 cm and the eye piece lens has a focal length fe = 3.0 cm; these two lenses are separated by a distance of 5.0 cm.
a) The sample is placed 0.22 cm away from the objective lens. What is the image distance?
b)What is the magnification of the object contributed by the objec- tive lens?
c)What is the image distance after the light interacts with the eye- piece lens? Hint: You will need to determine the distance of the image fromt he objective lens to the eye-piece lens.
d) Using your answer from part c), what is the magnification of the eye-peice lens?
e) If the initial object was 3μm what is the final image height?
