Questions and Answers

Match the following microscope parts with their functions:

Ocular = Allows the viewer to see the magnified image Stage = Supports the slide being viewed Condenser = Focuses light onto the specimen Light = Illuminates the specimen

Match the following microscope parts with their positions:

Light = Located at the base Revolving nosepiece = Holds multiple objective lenses Arm (neck) = Supports the body tube and connects to the base Mechanical stage knobs = Move the stage left and right or up and down

Match the following adjustment knobs with their purposes:

Study Notes

Resolution in Microscopy

Resolution is the capacity to deliver a clear image in fine detail, measuring lens quality.
It enables seeing small images clearly and distinguishing one point from another nearby.

Components of a Compound Light Microscope

A microscope consists of the following parts:
- Ocular
- Revolving nosepiece
- Objectives (scanning objective)
- Stage
- Iris diaphragm and lever
- Condenser
- Light
- N/OFF switch
- Coarse adjustment knob
- Fine adjustment knob
- Mechanical stage knobs
- Base
- Light intensity lever
Figure 2-1 illustrates the components of a compound light microscope.

Functionality of a Compound Light Microscope

A compound light microscope uses a combination of lenses to magnify an object.
The object is placed on the stage, which is illuminated by a light source.
Light passes through the object and then through a series of lenses.
The lenses magnify the image of the object, which is then projected into the viewer's eye.
