The diameter of the field of view of a microscope at 40X total magnification is 4.5 mm
Suppose you were viewing an object using a total magnification of 250X.
a) What is the field of view?
b) If your object takes up 1/4 of the field at 250X, what is the approximate size of your object?
Homework Answers
Magnification1 × diameter of field of view1 = magnification2 × diameter of field of view2
4.5 × 40x = diameter2 × 250x
Diameter2 = 0.72 mm
A. Area of field of view 2 = πr^2 = 22/7 × (0.72/2)^2 = 0.4073 mm^2
B. Size of object = 1/4 × 0.4073 = 0.1018 mm^2
Please rate high.
