Parts Of The Compound Light Microscope Quiz - Quiz

This should help you study the functions of a microscope for the Microscope Quiz on February 5th, 2009.


Questions and Answers
  • 1. 

    Where do you look into the microscope to see the image of the object you intend to study?

    Explanation
    The eyepiece, also known as the ocular, is the part of the microscope where you look to see the image of the object you intend to study. It is located at the top of the microscope and contains the lenses that magnify the image. By looking through the eyepiece, you can observe the details of the object under study.

    Rate this question:

  • 2. 

    Which part holds the two or three objective lenses, and rotates around in a circle, allowing you to choose which objective lens you want to use?

    Explanation
    The nosepiece is the part of a microscope that holds the two or three objective lenses. It is designed to rotate around in a circle, allowing the user to choose which objective lens they want to use. By rotating the nosepiece, different magnifications can be achieved, enabling the user to focus on different levels of detail in the specimen being observed.

  • 3. 

    What holds the upper portion of the microscope above the stage and is also where you grab the microscope anytime you decide to take it for a walk?

    Explanation
    The arm of a microscope is the part that holds the upper portion of the microscope above the stage. It is also the part that you grab whenever you decide to move or carry the microscope. The arm provides stability and support to the microscope, allowing it to be easily transported or adjusted during use.

  • 4. 

    This is so you can fine-tune the image...

    Explanation
    The fine adjustment knob is used to make precise adjustments to the image. It allows for small, incremental changes to the focus or clarity of the image. This knob is often used in conjunction with the coarse adjustment knob, which makes larger, more noticeable changes to the focus. The fine adjustment knob is especially useful when working with delicate or intricate subjects that require a high level of precision. By turning the fine adjustment knob, the user can achieve a clear and sharp image, ensuring that all details are properly captured.

  • 5. 

    What is the place where the goodies you want to examine are placed?

    Explanation
    The answer to the question is "Stage" because a stage is a designated area where items or performances are presented for examination or observation. It is commonly used in theaters, conferences, or events where goods or performances are showcased. The stage provides a platform for the items or performances to be displayed and examined by the audience or individuals.

    Rate this question:

  • 6. 

    What allows the light to come up from behind the object you're observing so that it's easier to see?

    Explanation
    The aperture refers to the opening in a camera lens that controls the amount of light that enters the camera. By adjusting the size of the aperture, more or less light can pass through, affecting the brightness and clarity of the image. In the context of the question, a larger aperture would allow more light to come up from behind the object being observed, making it easier to see.

    Rate this question:

  • 7. 

    What shines light up through the aperture and reflects light into the same space? It makes it easier to see the object on the slide.

    Explanation
    A mirror placed below the aperture can reflect light upwards, while a lamp positioned above the aperture can shine light through it. This combination allows the light to be directed into the same space, making it easier to see the object on the slide.

    Rate this question:

  • 8. 

    What holds the microscope in place?

    Explanation
    The legs of the microscope hold it in place. They provide stability and support, preventing the microscope from moving or tipping over while in use. The legs are designed to be sturdy and durable, ensuring that the microscope remains steady and secure during observations and experiments.

    Rate this question:

  • 9. 

    What's the long, skinny tube that holds the eyepiece above the microscope, and allows light to travel up from the objective lenses to the eyepiece?

    Explanation
    The body tube is the long, skinny tube that holds the eyepiece above the microscope. It is responsible for allowing light to travel up from the objective lenses to the eyepiece.

    Rate this question:

  • 10. 

    What are attached to the nosepiece and vary in size?

    Explanation
    Objective lenses are attached to the nosepiece and vary in size. These lenses are an essential part of a microscope and are responsible for magnifying the specimen being observed. Different objective lenses have different magnification powers, allowing the user to view the specimen at various levels of detail. By rotating the nosepiece, the user can switch between different objective lenses to achieve different magnifications.

  • 11. 

    More on the last question... Which different types are there?

    • A.

      Small, Big, and Bigger

    • B.

      High, Medium, and Low

    • C.

      Orange, Purple, and Green

    Correct Answer
    B. High, Medium, and Low
    Explanation
    The correct answer is "High, Medium, and Low" because these terms are commonly used to describe different levels or degrees of something. In many contexts, such as in rankings, measurements, or classifications, these terms are used to indicate varying levels of importance, intensity, or quantity. "High" typically represents the highest or most significant level, "Medium" represents an intermediate level, and "Low" represents the lowest or least significant level.

    Rate this question:

  • 12. 

    What's the large knob that allows you to move the upper portion of the microscope up and down so that you can focus on the slide? It is also usually on the arm.

    Correct Answer
    Coarse Adjustment Knob
    Explanation
    The large knob that allows you to move the upper portion of the microscope up and down so that you can focus on the slide is called the coarse adjustment knob. This knob is typically located on the arm of the microscope. It is used to make large adjustments to the focus of the microscope, bringing the slide into view.

    Rate this question:

  • 13. 

    What holds your specimens under the lens?

    Correct Answer
    Slide
    Explanation
    The correct answer is "Slide." A slide is a thin, flat piece of glass or plastic that holds specimens, such as cells or microorganisms, securely under the lens of a microscope. It allows the specimen to be easily viewed and observed under the microscope, providing a stable platform for examination and analysis.

    Rate this question:

  • 14. 

    What holds the microscope slide in place under the lens?

    Correct Answer
    Stage Clips
    Explanation
    Stage clips are used to hold the microscope slide in place under the lens. These clips are typically located on the stage of the microscope and are designed to secure the slide so that it does not move or shift during observation. This ensures that the slide remains in the correct position for accurate viewing and analysis under the microscope lens.

    Rate this question:

  • 15. 

    What allows you to change the amount of light that comes up through the aperture?

    Correct Answer
    Diaphragm
    Explanation
    The diaphragm is a part of the camera lens that can be adjusted to control the size of the aperture. By changing the size of the aperture, the amount of light that enters the camera can be increased or decreased. This allows the photographer to have control over the exposure of the image, as well as the depth of field. A larger aperture lets in more light, resulting in a brighter image and a shallower depth of field, while a smaller aperture lets in less light, resulting in a darker image and a greater depth of field.

    Rate this question:

  • 16. 

    What holds the whole microscope up?

    Correct Answer
    Base
    Explanation
    The base of a microscope holds the entire instrument up and provides stability and support. It is usually a flat platform that rests on the surface and keeps the microscope steady during use. The base also serves as a foundation for all other components of the microscope, including the arm, stage, and lens system. Without a solid base, the microscope would not be able to stand upright and function properly.
