A 5.0-mm focal-length objective lens and 60-mm focal-length eyepiece in a simple microscope are separated by a distance of 30 cm. If a human blood cell on a microscope slide is located 0.10 mm behind the focal length of the objective lens, what is the magnification of the microscope?

A microscope in the lab uses a lens with a focal length of 8.0 mm and an eyepiece with a focal length of 18 mm. The distance between the lens and the eyepiece is 19.7 cm. We use the microscope so that the eyes focus as if the object were placed infinitely far away. We treat the lenses as if they were "thin". b) How much linear magnification does the lens (alone) give?c) How much magnification does the eyepiece give alone?d) How is magnification defined for a microscope?e) What is the magnification of this microscope?

A compound microscope consisting of a shinny lens with a focal length of 10 mm and an eyepiece with a focal length (cm 2) and tube length (20 cm), what will the magnification be for the microscope? 350 450 O 550 250 O 150

The distance between the objective and eyepiece lenses in a microscope is 21 cm . The objective lens has a focal length of 5.0 mm .   What eyepiece focal length will give the microscope an overall angular magnification of 350?
