What is the function of the arm?
Answer:
It is used to support the microscope when carried.
Explanation:
The arm of the microscope is used to support the microscope when it is being carried. This suggests that the arm provides stability and balance to ensure that the microscope does not get damaged or dropped while being transported. The other options mentioned, such as looking through to see the specimen, holding the slide in place, and moving the stage up and down for focusing, are not the primary functions of the arm.
2.
What is the function of the stage clips?
Answer:
Hold the slide in place.
Explanation:
Stage clips are used to hold the slide in place on the stage of a microscope. This ensures that the slide remains steady and secure while viewing or examining the specimen. By holding the slide in place, stage clips prevent any movement or displacement that could affect the accuracy of the observations or the focus of the microscope.
3.
What is the function of the fine adjustment knob?
Answer:
Moves the stage slightly to sharpen the image.
Explanation:
The fine adjustment knob on a microscope is used to make small, precise movements to the stage in order to bring the image into sharp focus. This is especially helpful when using high magnification objectives, as even the slightest movement can cause the image to become blurry. By turning the fine adjustment knob, the user can make small adjustments to the height of the stage, allowing them to achieve a clear and detailed image.
4.
What is the function of the ocular lens?
Answer:
To look to see the specimen.
Explanation:
To look to see the specimen.Here's why:The ocular lens, also called the eyepiece, is the lens you look through to see the magnified image of the specimen. It magnifies the real image created by the objective lens, making it possible for you to see the tiny details.While the other options play important roles in microscopy, they are not the primary function of the ocular lens:Regulating the amount of light is done by the diaphragm, located below the stage.Projecting light upwards is the role of the condenser lens, positioned between the light source and the stage.Moving the stage up and down for focusing is achieved by the coarse and fine focus knobs.Therefore, the correct answer is 2.
5.
What is the function of the diaphragm?
Answer:
It is used to regulate the amount of light on the specimen.
Explanation:
The function of the diaphragm is to regulate the amount of light on the specimen. This is important in microscopy as it allows the user to control the brightness and contrast of the image being viewed. By adjusting the diaphragm, the user can optimize the lighting conditions for better visibility and clarity of the specimen.
6.
What is the function of the base?
Answer:
It supports the microscope.
Explanation:
The base of a microscope is responsible for providing stability and support to the entire microscope. It is designed to hold the weight of the microscope and prevent it from tipping over during use. Without a sturdy base, the microscope would be unstable and difficult to use.
7.
What is the function of the stage?
Answer:
It supports the slide being viewed.
Explanation:
The function of the stage is to support the slide being viewed. The stage holds the slide in place and provides stability while the slide is being observed under the microscope. This allows for accurate positioning and focusing of the slide, ensuring clear and precise examination of the specimen.
8.
What is the function of objective lenses?
Answer:
Magnification ranges from 4x to 100x.
Explanation:
The function of objective lenses in a microscope is to provide magnification. They are responsible for enlarging the image of the specimen being viewed. The given answer correctly states that the magnification ranges from 4x to 100x, indicating that the objective lenses have the capability to increase the size of the specimen by 4 to 100 times. Different types of objective lenses have differing ranges: Scanning Objective Lens (4x), Low Power Objective (10x), High Power Objective Lens (40x), Oil Immersion Objective (100x).
9.
What is the function of the light source?
Answer:
Projects light upwards through the diaphragm, the specimen, and the lenses.
Explanation:
The function of the light source is to project light upwards through the diaphragm, the specimen, and the lenses. This allows the specimen to be illuminated and visible for observation.
10.
What is the function of the coarse adjustment knob?
Answer:
Moves the stage up and down for focusing.
Explanation:
The function of the coarse adjustment knob is to move the stage up and down for focusing. This allows the user to adjust the distance between the objective lens and the specimen, bringing it into clear focus. The coarse adjustment knob is used to make larger adjustments to the focus, while the fine adjustment knob is used for more precise focusing.
