The area of the slide that you are observing through the microscope is called? - answer✔✔Field-
of-view
The ability of a lens to show two adjacent objects as discrete entities is called?
How far apart two adjacent objects must be before a given lens show the discrete entities -
answer✔✔Resolving power:
Fine-adjustment knob- - answer✔✔for sharp focusing, used with high power objective 40x and
small knob, once object is in view and you go higher in magnification, you use this knob to put
objects into focus. This knob is used to raise and lower the body tube and is used to magnify the
10x, 40x, 100x objective lenses

knob), to use at lower magnifications to bring sample into view. This knobs is used to raise and
lower the body tube and is used only to magnify the 4x scanning power objective.
immersion oil - answer✔✔Because air has a lower refractive index than glass, light waves tend
to bend and scatter as they pass through the air from the glass slide to the 100x objective lens.
Adding
_________ which has the same refractive index as glass, diminishes the loss of refracted light
and improves resolution.
