4) Answer true or false to each of the following statements. On high power, you should use the coarse adjustment knob. The diaphragm determines how much light shines on the specimen. The low power objective has a greater magnification than the scanning objective. The fine focus knob visibly moves the stage up and down. Images viewed in the microscope will appear upside down. If a slide is thick, only parts of the specimen may come into focus. The type of microscope you are using is a scanning microscope. For viewing, microscope slides should be placed on the objective. In order to switch from low to high power, you must rotate the revolving nosepiece. The total magnification of a microscope is determined by adding the ocular lens power to the objective lens power.

PART C: CALCULATING THE DIAMETER OF THE FIELD OF VIEW (FOV)_ The field of view (FOV) is the circular area you can see when you look through the microscope. The diameter of the field of view is different depending on which objective lens you are using. For example, you are using the medium-power objective lens, then the area you can see is actually smaller than if you were using the low-power objective lens. Knowing The diameter of the field of view can help you estimate actual size of objects / cells seen through the microscope. When the revolving nose piece is turned to the low power objective lens, a dear plastic ruler can be placed on the microscope stage (see figure 1). Then, the coarse adjustment knob can be used to focus on the millimeter marks of the ruler making sure that one of the milimeter marks is at the left edge of the field of view (see figure 2). NOTE: Slage cip I-1000 Objects in the FOV are usually measured in micrometers (um). To convert, a FOV in mm, times it by 1000…
