What is the use of the coarse adjustment knob?
The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.
What does the coarse focus knob on a microscope do?
The coarse focus on a microscope is provided to move the instrument quickly to where it is nearly in focus. Some microscopes only have a coarse focus. The fine focus is used to move with slower and more precise adjustment to where the instrument is exactly in focus.
What does the coarse adjustment do on a microscope?
The coarse focus adjustment moves the lens (or the stage, depending on the construction of the microscope). So does the fine adjustment but the fine does it much less and much more accurately (less play in the gears)
What is the large knob on the side of a microscope that should be used first when viewing a slide?
This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.
How does the procedure for using the microscope differ under high power as opposed to low power?
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
