How should the condenser and diaphragm be adjusted for optimal viewing?

The condenser should be raised to the uppermost position. This maximizes the amount of light entering the objective lens and minimizes the amount lost to refraction.
The diaphragm should be stopped down just enough to provide an acceptable image. The best results are usually obtained by beginning an examination on low power with the diaphragm almost completely closed.

How should the condenser be set when viewing bacteria?
The condensor of microscope is used to control the light intensity so it first depends on the viewer and secondly it should be so adjusted so that the light intesity does not shoots high as it can damage the specimen and is also harmfull to the eyes and even to the microscope. It is also to be see that the specimen view clearly against its background.

What are the names of the parts of the microscope that change the magnification?
I. Magnifying Parts 1. Ocular/Eyepiece-magnifies specimens by 10-15 times 2. Objectives: a. Low-Power Objective- 10-15 times-general view of the specimen b. High-Power Objective- 43-100 times-detailed parts of the specimen c. Scanning Lens- 5 times-general view of the specimen d. Oil Immersion Objective- 1000 times-used only for viewing bacteria; needs cedar oil II. Illuminating Parts 1. Mirror- reflects light 2. Condenser- concentrates light 3. Sub-stage Condenser- allows light to pass 4. Iris Diaphragm- controls the passage of light
