Chapter 4 Microscopes Two important factors in microscopy are: 1) Magnification: an increase in the object’s apparent size compared with its actual size. 2) Resolving Power: the ability of an optical instrument to show two objects are separate. Three types of microscopes: 1) Light Microscope (LM) M: 1000x RP 0‚2 micrometer (small bacterial cell) 2) Electron Microscope (EM) uses a beam of electrons to resolve electrons‚ better resolving powers than light microscope M:100‚000x RP 0
