Answer:
Step-by-step explanation:
Assuming that the field of view is directly proportional to the magnification, we can use the following formula to find the diameter of the field of view at 80x magnification:
d2 = (m2/m1) * d1
where:
d1 is the diameter of the field of view at 40x magnification, which is 4mm
m1 is the magnification at which the diameter of the field of view is measured, which is 40x
m2 is the magnification at which we want to find the diameter of the field of view, which is 80x
d2 is the diameter of the field of view at 80x magnification, which is what we are looking for
Plugging in the values, we get:
d2 = (80/40) * 4mm = 8mm
To convert millimeters to microns, we need to multiply by 1000. Therefore, the diameter of the field of view at 80x magnification is:
d2 = 8mm * 1000 = 8000 microns
So the diameter of the field of view at 80x magnification is 8000 microns.
