23
Q

2 lenses, uses light rays, magnifies up to 2000x, good resolution, can view images .2 microns or larger, can view living specimens

A

compound light microscope

24
Q

uses an electron beam, magnifies up to 2,000,000x, excellent resolution, can view images .2 microns or smaller, can only view dead specimens

A

electron microscope

25
the least distance between 2 points in which they are seen as 2 points
resolution
26
the area that we see while looking under the microscope, the area decreases with increased magnification, illumination decreases
