Question
Chapter 4, Problem 5CT
Summary Introduction
To answer:
To find the resolution of two objects at 400nm and 40nm apart by using 100× oil lens.
Introduction:
A microscope is a device used to view the magnified image of an object. There are two types of lens used in the microscope namely, the objective and the ocular lens. The ocular lens has 10× power and the objective lenses have 10×, 40×, and 100× power respectively.
The resolving power of a microscope was increased by using the immersion oil. It was attained by immersing the objective lens and the slide containing the sample in a transparent oil. The 100× objective lens is used for the oil immersion procedure.

Please explain the table
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?
How do you know?
Using a good compound light microscope with a resolving of 0.3 micro meter a 10x ocular lens ,and a 100 x oil immersion lens, would you be able to discern two objects separated by 0.4 micro meter?0.2 micro meter? 300 neno meter ? Explain your reasoning.

- Assume you are observing the diatom pictured in Figure 1 using the 10X lens in a compound light microscope. You move to the 40X lens and then again to the 100X lens by only rotating the turret (remember that the lenses are parfocal), without making any other adjustments to the microscope. c) After making your adjustments, you notice that the midline of the diatom is in focus while the remainder is blurry.
