Which part of the microscope is used to make small adjustments in the image of an object?
Rus_ich [418]

Answer:

The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.

Explanation:

In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied.  This means making minimal adjustments in order to better observe the microscopic image.

After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.

The other options are not correct because:

<em>     A. </em><em><u>Eyepiece</u></em><em>  is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.</em>

<em>     C. </em><em><u>Coarse Adjustment  </u></em><em>is the rough magnification, used for the initial approximation of the image.</em>

<em>     D. </em><em><u>Objective lens</u></em><em> enlarges and defines the image of the sample on the slide.</em>
