Question

part 2: structure functions
complete the table below to describe the function of each of a compound light microscope’s main structures.

structure	function (how does it work / what does it do?)
revolving nosepiece	the revolving nosepiece rotates to see the different lenses.
diaphragm	the diaphragm adjusts brightness and the contrast of the image.
stage clips	the stage clips hold the slide securely.
light source	the light source makes the specimen visible to help view under the lenses.

coarse adjustment
fine adjustment
objective lens

Explanation:

To complete the table for the compound light microscope structures:

Coarse Adjustment

The Coarse Adjustment knob is used to make large adjustments to the focus of the microscope. It moves the stage (or the objective lens, depending on the microscope design) up and down significantly to quickly get the specimen approximately in focus.

Fine Adjustment

The Fine Adjustment knob is used for making small, precise adjustments to the focus. After using the coarse adjustment to get close to focus, the fine adjustment is used to sharpen the image and get a clear, detailed view of the specimen.

Objective Lens

The Objective Lens is the lens (or set of lenses) closest to the specimen on the slide. It magnifies the specimen, and different objective lenses (e.g., low-power, high-power) provide different levels of magnification to view the specimen in more or less detail.

If we were to put these into the table:

Structure	Function (How does it work / what does it do?)
Fine Adjustment	Makes small, precise focus adjustments to sharpen the image of the specimen.
Objective Lens	Magnifies the specimen on the slide (different objective lenses provide different magnification levels).
