A student has a compound microscope equipped with 10X ocular lenses and 4X, 10X, 40X and 100X objective lenses. The student has a slide with cells that are -50 microns (1 micron = 10 mm) in diameter, and wants to view a magnified image of a cell so that the cell appears to be 20 mm in diameter. Which objective lens should the student use? 10X
