A student using a microscope measured the low power field diameter to be 7.1mm. The student then switched from the low power (4x) objective lens to the medium-power (10x) objective lens. Assuming a 10 x ocular (eyepiece) lens, the medium power field diameter is ____ um um is micrometers
Shown below are several micrographs (images from microscopes) that were taken using different microscopy techniques. Write down what method of microscopy was used and why you thought so. Choices for microscopy techniques are: Transmitted Light Microscopy (techniques of brightfield, phase-contrast, darkfield, DIC all fall under this), Fluorescence Microscopy, Scanning Electron Microscopy, and Transmission Electron Microscopy.

You have placed a microscope slide in a microscope and want to view it at with the 10X objective lens. List the steps that are necessary to set up and focus the microscope properly using the 10X objective lens.
Label the parts of the microscope on the diagram below: arm, stage, base, ocular, revolving nosepiece, objective (4x, 10x, 40x), course focus, fine focus, condenser & iris diaphragm (these are marked by the same line)
Using the provided materials and the microscope itself, review the parts of the microscope including the name, where it is located, its function and the appropriate times to use. Record your observations and notes as vou will require this information when writing yourlab report
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. Lens that condenses light through the specimen and is located below the stage. 7. Light from specimen passes through these lenses first. These lenses are located in the rotating nosepiece. 8. Wide bottom part that supports the microscope. 9. Regulates the amount of light passing through the condenser. 10. Vertical portion that connects the base to the head.
