Detailed explanation-1: -Look through the eyepiece (1) and move the focus knob until the image comes into focus. Adjust the condenser (7) and light intensity for the greatest amount of light. Move the microscope slide around until the sample is in the centre of the field of view (what you see).
Detailed explanation-2: -You must have the object centered before you change objectives to increase the magnification, because the field of view becomes smaller; if the object is off to the side, it may disappear when you go to higher magnification.
Detailed explanation-3: -Then, we focus the specimen again and view it nice and closely. Therefore, the correct answer to this question is (B). Select low-power objective then place slide on stage then turn coarse focus then turn fine focus then select medium-power objective.
Detailed explanation-4: -Important Note: Before switching to high power, you should always position the specimen in the center of the field of view and use the fine adjust to sharpen the focus of the image. Never use the coarse adjustment when using high power.
Detailed explanation-5: -Step 1: Connect the light microscope to a power source. Step 2: Turn the revolving nosepiece so the lowest objective lens is in position. Step 3: Mount your specimen onto the stage. Step 4: Use the metal clips to keep your slide in place. More items
