Chapter 1.5, Problem 1CR
Summary Introduction
Microscope is a fundamental tool used to study the size and shape of the microorganisms. It magnifies the cell size and other smaller objects. In order to visualize microorganisms, the microscopes are the right choice to view their size and shape of the cells. A typical microscope consists of an eyepiece, objective lens, and light illuminator to visualize the cells or small objects with good magnification and resolution abilities.

In spectrophotometry, what is the role of the green background in the set-up? What does it represent in the actual spectrophotometer?
Define each of the following terms:
A) What is resolution and how is resolution related to the wavelength of light used to illuminate the sample?
B) What is the magnification of the specimen if you are using a 40x objective and a 10x eyepiece?
C) How is the numerical aperture (NA) of a lens related to its ability to gather light from a specimen?
The field of view (FOV) is the entire circular image we see when looking into the eyepiece. The diameter of the FOV gets smaller as we increase magnification. It can be measured by using a stage micrometer like a ruler, measuring from edge to edge. Notice that the stage micrometer is 1000 microns (µm) in length, and the field of view under the lowest magnification is 5000 µm. Describe how we measure it?
