it is used as fine adjustment to increase resolution of microscope
The depth of field is so small that a very small vertical travel could shift the focus from the top of the specimen to the bottom. A very fine adjustment must be used, which is why the coarse adjustment screw is implemented.
The function of a microscope's coarse adjustment knob is to improve focus on the object under study by adjusting the lens. Unlike the fine adjustment, coarse adjustment moves the lenses quickly.
The working distance decreases when going from low power to high power magnification. This is because higher magnification lenses have shorter focal lengths, requiring the object to be placed closer to the lens to come into focus.
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.
Nothing will happen because the coarse adjustment knob controls the position of the stage of the microscope, which is used to focus the specimen. This adjustment is independent of the choice of objective lens.

No, you should not move the course adjustment while on high power as it can damage the microscope or the specimens in view. It is recommended to make adjustments to the course adjustment only while on low power.
