Detailed explanation-1: -The coarse and fine focus knobs on a microscope enable you to adjust the focus of the microscope to get the best view of the specimen possible. Remember to use the coarse focus knob only with the 4x objective, and the rest of the time use the fine focus knob.
Detailed explanation-2: -The answer is false. When focusing on high power while using a microscope, always use the fine adjustment knob to focus. This is because the working distance is extremely small and using the coarse adjustment knob risks cracking the glass slide or objective lens.
Detailed explanation-3: -Answer and Explanation: The above-mentioned statement is True. The coarse adjustment knob is used to focus the object. This knob is used with the low power objective lens as well as the scanning objective lens.
Detailed explanation-4: -to adjust the image at each of the magnifications. CAUTION: NEVER, EVER, use the coarse adjustment knob with the high power objective. This could break the lens. Multiply the power of the ocular lens, by the power of the objective lens.
