It depends on the particular microscope, and the magnification being used.
Without these details, this question cannot be answered.

What is darkfield microscopy?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'
What are the disadvantages of the scanning tunneling microscope as compared to a conventional microscope?
The best way to illustrate the disadvantages of the scanning tunneling microscope (STM) over a conventional microscope might best be shown by a comparison. Imagine using a pair of field glasses to watch birds in a heavily wooded area. Now imagine watching those birds in the same area with an 8" reflecting telescope and a "big" eyepiece. You could be looking at a bird with the telescope and not know it because you wouldn't even be able to see the whole bird.The STM can map a single atom on the surface of a sample with its probe, but it cannot show us the shape of a single celled animal because it is extremely powerful -- too powerful for that application. The microscope is something we can use all day to study tiny animals like, say, an amoeba.
Rules to follow when handling a microscope?
1. Always carry the microscope in an upright position with two hands. One hand should support the base and the other should be on the on the arm. Use lens paper and lens cleaning solution to clean the lenses on the microscope. Paper towel will scratch the lenses. Use a soft cloth to clean other parts of the microscope. Lens cleaning fluid and paper is a must. Do not substitute paper towel, which is far too coarse and will scratch the lenses. Always set your microscope on a clean, flat surface. 5. Always remove slides from the stage and rotate the nosepiece to the lowest power before returning the microscope to its storage area.
What is proper ways of handling and manipulation microscope?
Manipulate a MicroscopeInstructions1Set up the microscope on a flat surface. Always carry the microscope using two hands if the microscope must be transported from one area to another. One hand should support the bottom while the other hand is holding the arm. Once in place, remove the any covers and plug in the microscope.2Position the slide onto the stage. Clip it into or under the slide holders. Turn on the light from the illuminator under the stage. Center the slide the best way possible without using any focusing knobs or the eyepiece.3Look through the eyepiece, keeping both eyes open to avoid eye strain, while using the course focus knob to bring the stage and slide closer to the objective, which is the lens that extends below the eyepiece, until the object can be seen through the eyepiece. Use the fine focus knob (which will also be on the side of the microscope) to bring the image into sharper focus.4Center the object being viewed. Change the iris diaphragm under the stage using the level to open and close the iris. Change the amount of light entering the specimen as needed. Changing the amount of light going through the slide may show additional details not seen at higher light levels.5Change to the 10X objective which is the next longest lens by rotating the lens pieces. The object should appear larger and only require using the fine focus knob to bring it into sharper detail. Use the iris diaphragm to change the amount of light entering the slide. Continue to the 40X objective and repeat. Each time the object will appear larger and you will be able to see less of the object at any one time while viewing.6Lower the stage and add one or two drops of immersion oil to the slide. Change the microscope to the 100X objective. Slowly raise the stage using the course focus until the objective is touching the oil. Use the fine focus knob to bring the object into sharp focus. Clean the slide and objective with lens tissue after use.7Return the stage to the lowest level. Change the objective back to the 4X lens. Unplug the machine and replace any covers. Carefully return the microscope using both hands to where it is stored.
Can a magnifying glass make a laser stronger?
Yes, it can. A microscope can focus a laser beam in a smaller spot then it was creating a higher energy density per unit area.
The area of the specimen seen when looking through the microscope is called?
Field
Is what you look under a microscope is a specimen?
Yes - but a specimen can be something that is not observed under a microscope as well. For example, if you ever went on a walk in the country, picked a wildflower that grew there, and brought it home, you would have a specimen of a native plant that grew in the area where you found it.
Is what you look at under a microscope called a specimen?
Yes - but a specimen can be something that is not observed under a microscope as well. For example, if you ever went on a walk in the country, picked a wildflower that grew there, and brought it home, you would have a specimen of a native plant that grew in the area where you found it.
What is the microscope's field of view?
It is the area that you see when looking through the microscope. The field of view depends on the strength of magnification. The lower the power the larger the field of view.
As the magnification increases what decreases in a microscope?
The visibility of the specimen decreases as the power of magnification increases on a microscope. The specimen area will shrink as the magnification is increased.
What the bottom part of the microscope?
1. Ocular Lens (Eyepiece) - where you look through to see the image of your specimen. Magnifies the specimen 10X actual size. 2. Body tube - the long tube that supports the eyepiece and connects it to the objectives. 3. Nosepiece - the rotating part of the microscope at the bottom of the body tube; it holds the objectives. 4. Objective Lenses - (low, medium, high). Depending on the microscope, you may have 2, 3 or more objectives attached to the nosepiece; they vary in length (the shortest is the lowest power or magnification; the longest is the highest power or magnification). 5. Arm - part of the microscope that you carry the microscope with; connects the head and base of the microscope. 6. Coarse Adjustment Knob - large, round knob on the side of the microscope used for "rough" focusing of the specimen; it may move either the stage or the upper part of the microscope. Location may vary depending on microscope - it may be on the bottom of the arm or on the top. 7. Fine Adjustment Knob - small, round knob on the side of the microscope used to fine-tune the focus of your specimen after using the coarse adjustment knob. As with the Coarse Adjustment Knob, location may vary depending on the microscope. 8. Stage - large, flat area under the objectives; it has a hole in it (see aperture) that allows light through; the specimen/slide is placed on the stage for viewing. 9. Stage Clips - clips on top of the stage which hold the slide in place. 10. Aperture - the hole in the stage that concentrates light through the specimen for better viewing. 11. Diaphragm - controls the amount of light going through the aperture; may be adjusted. 12. Light or Mirror - source of light usually found near the base of the microscope; used to direct light upward through the microscope. The light source makes the specimen easier to see.
What is the function of the high power objective on a microscope?
The high power objective on a microscope increases the magnification of the specimen, which allows you to see more detail. It allows you to see a close up of only a small area of the specimen being viewed.
The circular area of light you see when you look through a microscope is?
field of view
What type of microscope provides the greatest resolution?
Depth of field in a microscope refers to the distance between the nearest and the furthest objects that produce a distinct image of a specimen. It is usually very short and is measured in microns.
What secures the slide for viewing in the microscope?
In a traditional light microscope, the slide is secured using a mechanical stage or stage clips. The mechanical stage allows for precise positioning of the slide, while the clips hold it in place to prevent movement during observation. This ensures that the slide remains stable and the microscope can focus on the desired area of the specimen.
What does a diaphram do on a microscope?
The diaphragm is a circular disk that adjusts the amount of light entering the stage area.
Where is the cell nucleolus?
It is in nucleus.You can see a darker circular area in nucleus when observed an eukariyotic cell through a microscope.
