Chapter 4, Problem 12TYK
Summary Introduction
To review:
There are many compound microscopes which have a filter that eliminates all the wavelengths except that of the blue light and thus, it allows only blue light to pass through the microscope. The filter improves the resolution of the light microscope.

The magnification possible with any type of microscope is an important property, but its resolution, the ability to distinguish between two very closely apposed objects, is even more critical. Describe why the resolving power of a microscope is more important for seeing finer details than its magnification.
If I also observe something let's say if I was I was 50 nm inside which microscope would you recommend me using?
In the image is that the correct answer to the question
3D dimensionality is a limitation of the compound
microscope. Depth of field, DOF, describes dimensionality
form top to bottom and can be observed with colored cross
threads. Observe the crossed thread slide on low power
(4x), then on medium power (10x), then on high power
(40x objective magnification).
Which crossed fiber is on top?

- The field of view is the maximum area visible through the lenses of a microscope, and it is represented by a diameter. To determine the diameter of your field of view, you can place a transparent metric ruler under the low power (10X) objective of a microscope. You would focus the microscope on the scale of the ruler and measure the diameter of the field of vision in millimeters. Refer to the image taken of this preparation below. What is the approximate field of view as seen by this 10X objective.
