A lab revolving around compound microscopes was conducted. Please answer the following questions (questions 1, 2, and 3). If a specimen (placed on a slide) has little or no color, what level of light intensity should you use; should the intenisty of the light be high or low (choose)? Which objective should be in position before you start to focus the microscope? Which focus knob should you use first with this objective?
Using the microscope Answer the following questions as you work through this exercise: 1. How is the letter “e” on the slide oriented when you see it with the naked eye as you mount it on the stage (i.e., is it right side up or upside down)? 2. How is the letter “e” on the slide oriented when you see it under low or high power magnification? 3. What effect, if any, does the compound light microscope have on the orientation of the image?

Write the term that the phrase describes. 1. Large knob that moves the stage or objective lens a great distance. Used with scanning or low-power objective lenses only. 2. Flat platform beneath the objective lens on which the microscope slide is placed. 3. Removable lenses that you look through to observe the microscope slide. 4. Small knob that moves the stage or objective lens a very small distance and is used for precision focusing. 5. Extends from the arm and contains the ocular lenses and rotating nosepiece. 6.
