  • 2. 

    True or False.  If false, correct what is in ( ). When beginning to focus, use the (lowest power) lens.

    Explanation
    When beginning to focus, it is recommended to use the lowest power lens. This is because the lowest power lens provides a wider field of view, which makes it easier to locate and center the object of interest. As the focus becomes clearer, higher power lenses can be used to magnify the details.

  • 3. 

    True or False.  If false, correct what is in ( ).  The microscope lens my be cleaned (with any soft tissue).

    Explanation
    The correct answer is false because the microscope lens should only be cleaned with special grit-free lens paper. Using any soft tissue may scratch or damage the lens surface. It is important to use the proper cleaning materials to ensure the lens remains in good condition and does not affect the quality of the microscope's performance.

    Rate this question:

  • 4. 

    True or False.  If false, correct what is in ( ). The microscope should be stored with the (oin immersion) lens in position over the stage.

    Explanation
    The correct answer is false because the microscope should be stored with the lowest power objective lens in position over the stage, not the oil immersion lens. The oil immersion lens is typically used for high magnification and requires special care and maintenance, so it should not be left in position when the microscope is not in use.

    Used to increase the amount of light passing through the specimen.

    Explanation
    The condenser is a component in a microscope that is used to increase the amount of light passing through the specimen. It is located beneath the stage and focuses the light onto the specimen, making it easier to see and analyze. By adjusting the condenser, the user can control the intensity and angle of the light, enhancing the clarity and visibility of the specimen.

    Rate this question:

  • 6. 

    Secure(s) the slide to the stage.

    Explanation
    The correct answer is mechanical stage, spring clips, or mechanical stage or spring clips. This means that in order to secure the slide to the stage, you can use either a mechanical stage or spring clips, or you can use both of them together. Both options are valid and will effectively secure the slide in place.

    Rate this question:

  • 7. 

    True or False.  If false, correct what is in ( ). A coverslip should always be used (with wet mounts and the high-power and oil lenses).

    Explanation
    A coverslip is not always necessary when using high-power and oil lenses. These lenses are designed to be used with a thin layer of immersion oil between the lens and the specimen, which eliminates the need for a coverslip. However, when making wet mounts, a coverslip is typically used to prevent the specimen from drying out and to provide a flat surface for viewing. Therefore, the correct statement would be "A coverslip should always be used with wet mounts, but not necessarily with high-power and oil lenses."

    Rate this question:

  • 8. 

    True or False.  If false, correct what is in ( ). When focusing, always focus (toward) the specimen.

    Explanation
    When focusing, it is not always necessary to focus towards the specimen. In some cases, it may be more appropriate to focus away from the specimen.

    Rate this question:

  • 9. 

    Delivers a concentrated beam of light to the specimen

    Explanation
    The iris diaphragm is a device in a microscope that controls the amount of light passing through the specimen. By adjusting the size of the aperture, it can deliver a concentrated beam of light to the specimen. This allows for better visibility and clarity when observing the specimen under the microscope.

    Rate this question:

  • 10. 

    Colored threads increases____/____

    Explanation
    When colored threads are added, they create a visual effect that increases the depth of field or depth of focus. This means that the range of distance in the image that appears sharp and in focus is expanded, resulting in a greater perception of depth. The addition of colored threads adds visual cues and enhances the perception of space and distance in the image.
