Homework Answers
And 1) the letter "e" looks upside down under compound microscope. Pic attached for the drawing.
And 2) if you move the slide to right the image moves to the left.
And 3) When changing objectives from scanning power to lower power to high power ( 4x to 40x) the following changes will occur:
a. the size of the field of view decreases.
b. the field of view is darker.
c. the size of the image increases.
d. the resolution (ability to separate small details) increases.
e. the working distance (distance between coverslip & objective) decreases.
And 4) as we move from 4x to 40x the field of view is darker or less bright.

The micrographs in this document are from a cross-section of the small intestine. This image is part of the field of view using a 10X eyepiece and a 4X objective, providing a total magnification of 40X. The digital camera image here is approximately 2/3 of the visual field of view, giving an actual magnification of about 60X. What tissues are visible here? For a closer look, change the size of the...
