Jacob is unsure about how to focus a slide under the microscope. What would be Jacob’s best course of action?
Answers
In the given case, Jacob should ask the teacher for instructions.
One should follow the following steps in order to view the prepared slides:
1. Initiate by rotating the objective lens to the lowest power.
2. Place a slide on the stage, label side up, with the coverslip in the center.
3. Use the coarse focus knob to get the object into focus with low power only.
4. If one is not able to witness anything, then move the slide slightly while observing and focusing.
5. However, if nothing is there, then minimize the light and repeat the above step.
6. Once focusing on low power, center the desired object by moving the slide.
7. Rotate the objective to the medium power and amend only the fine focus.
8. If required, then rotate the objective to the high power and amend only the fine focus.
