Functions of the light mlcroscope parts Complete the following table by writing the function(s) of each of the parts indicated. Structure Function Diaphragm / iris Stage opehing Lamp Objective lenses Eye piece Coarse and find adjustment knobs Stage Stage rack prt sc delete home backspace lock enter pause t shift9:06 LTE 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.
