It is focused on the largest area of vision by being the most "zoomed out", so you are looking at a much greater area than the high power field of view.
area of object = (1/3) pi * radius^2 = (1/3) (pi) * (0.6)^2 = 0.377 Find the diameter of this object (assuming it's a circle), and that's the answer: diameter = radius * 2 radius = square root (area / pi) diameter = 2 * square root (area / pi) diameter = 2 * (0.335) = 0.67
The field of view is inversely related to the magnification power...the greater the magnification, the smaller the field of view
Medium power objective gives the medium (as oppose to large or small), field of vision and the greatest depth of field. When you move the lens' position (CLose or far from the slide) it would be the middle. Read the textbook it will be of more benefit; or look it up on the internet you are on anyways.

Depth of field decreases from low to high. This means what you see under the microscope is blurry. If both objects are not blurry, this means you have high depth-of-field.
The difference of the near point and far point of vision of the eye. D= 1/Op - 1/Or The difference of the near point and far point of vision of the eye. D= 1/Op - 1/Or
The diameter of a field is decreased by 1.5 millimeters when changed from low power to high power magnification.
the diameter of the high power field microscope is 500 micrometers
You use the 3 objective lenses of a compound microscope to switch powers. There's LOW, MEDIUM, and HIGH power. With LOW power, you can magnify what you're looking at. With HIGH power, you can see things that you can't see with a naked eye.
At low power on the compound microscope, the diameter of the field of view is 4 millimeters. This is reduced to 1.7 millimeters when you switch to medium power
The high power field, though more magnified, covers a much smaller slice of the field of vision. If not centered the e could disappear to one side or the other.
At low power on the compound microscope, the diameter of the field of view is 4 millimeters. This is reduced to 1.7 millimeters when you switch to medium power and further reduced to 0.4 millimeters when you switch to high power. Covert the measurment for the field of view from millimeters to microns, the conventional unit of measurment in microscopy. There are 1000 microns in one millimeter. Low power: 4mm= 4,000um Medium power: 1.7mm= 1,700um High power: 0.4mm= 400um
The equation goes like this and works for both medium AND high feild diameter : Medium(High) DIA. = Low Diameter / [Med(High)mag/low mag] Brackets () are NOT for multiplication, they are for the other formula.

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.
