Question

Often what you want to visualize is not in the middle of the field of view and you must move the slide around to find what you want to study. To move the slide, you move the stage. As you look at the microscope, the stage knob on the top moves the stage forward and back. The stage knob on the bottom moves the stage side to side.

a) Coarse focus moves the stage forward and back, and fine focus moves the stage side to side.
b) Coarse focus moves the stage side to side, and fine focus moves the stage forward and back.
c) Coarse focus moves the stage left and right, and fine focus moves the stage up and down.
d) Coarse focus and fine focus are used interchangeably to move the stage.

Answer 1

When focusing a light microscope, it is best to adjust the focus using the coarse focusing knob before using the fine focusing knob.

Step-by-step explanation:

When focusing a light microscope, it is best to adjust the focus using the coarse focusing knob before using the fine focusing knob. The coarse focusing knob moves the stage forward and back, while the fine focusing knob is used for small-scale movements. This is because the coarse focusing knob is designed for large-scale movements, which helps to quickly bring the specimen into focus, while the fine focusing knob allows for more precise adjustments to achieve optimal clarity.
