### Suppose the diameter of the field of view using the scanning lens is 4.0 mm What is the diameter of the field of view of an objective that is 10X?

The answer is 1.6mm.
The magnification is inversely proportional to field of
view.
Therefore, the calculation should be as follow:
Diameter of the f.o.v of low power lens (10x) / Diameter of the
f.o.v of scanning lens (4x) = Scanning lens magnification (4x) /
Low power lens magnification (10x)
k/4=4/10
k= (4/10) x 4
k= 1.6mm
Note: f.o.v= field of view

### What does it mean for a microscope to be parcentered?

When a microscope is parcentered, the specimens will appear
centered in the field of view at every magnification. So if a field
of a slide is centered at the lowest power, even though the field
diameter shrinks at each higher magnification, the desired part of
the specimen will remain in the center of the viewing field.

### When using a 10X ocular and a 15X objective and the field size is 1.5 mm the approximate field size with a 30X objective is what mm?

0.75 mm
way to get this answer...........
(diameter of field A X total magnification of field A) / total
magnification of field B
so start by finding the diameter of field A= which is the
1.5
next figure out what the total magnification of field A is= 150
(you get this answer by multiplying the ocular # which is 10x by
the objective # which is 15x.
(10 x 15= 150)
next figure out what the total magnification of field B is =300
(you get this answer by multiplying the ocular # which is 10x by
the other higher objective # which is 30x.
(10 x 30 = 300)
then you can use the formula and plug in all the answers you got
to get the answer
(1.5mm x 150)/300=.75mm

### What is the relationship between total magnification and the field of view?

as the magnification increases, your field of view decreases. so
when your magnification decreases, your field of view increases.
such as, for example, a brick wall. when your 2 blocks away from
one, all you see is the brownish wall. that is the low power
objective. then when you get right up to the wall, you see all the
tiny details. that is the high power objective. just think about it
like that. =D. i hope it helped
