Question

a punctuation mark "." measuring 2.0 microns is examined in the microscope. given a magnification of 10x forocular, 10x for LPO, 45x for HPO, and 95x for OIO, how big will its virtual image be?

Answer 1

At LPO, the maginfication would be 10 x 10, or 100X and so would be 200 microns (or 0.2mm).  At HPO it would be 10 x 45 or 450X and would appear 900 microns (or 0.9mm).  At OIO magnification would be 10 x 95 or 950X and would appear 1900 microns (or 1.9mm).
