A microscope has an objective with a 4 mm focal length and an ocular with a 30 mm focal length. The two lenses are separated by 0.16 m, and the final image is formed 0.25 m from the ocular.
a. Where is the image formed by the objective?
b. Where is the specimen relative to the objective?
c. What is the magnification of the microscope?
d. Neglecting any diffraction effects, what is the smallest separation between two points that can be resolved by the eye with this microscope? Assume that the smallest resolvable separation of two points for an unaided eye is about 0.1 mm.
