How does magnification and resolution affect the appearance of objects viewed under a microscope?
well, if you are trying to see something microscopic, you can look though a microscope to see it. but, if the microscope is in a very high scope, ex 1000x, you need to adjust the height of the scope using a knob on the side.
How do you work a microscope?
A confocal microscope works by a laser shining on two mirrors mounted on motors which allows it to scan the sample then the emitted light is focued through the pinhole to a detector which relays an image to the lens.
When using a microscope if there is an object on the left side of the field that you want to bring to the center in which direction should you move your slide?
right
How do you convert a glass sheet into mirror?
if you made one side of mirror opaque,other side will become a mirror.
What does a transmission electron microscope tem allow a scientist to do?
1.in EM instead of ordinary light a particle beam of electrons is usedto illuminate the samle or the specimen. 2.it has a very good resolving power. 3.it used to examin very tiny particles such as viruses or virion which consists of RNA or DNA and a protein coat,also utilised in illustrating body cells and other micro-organisms.....thx......with best regards..
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.
Why must you use a thin specimen when viewing with a light microscope?
For a light transmission microscope, a thin sample is needed in order for the light to pass through the sample from the light source on the other side. However, you can use a dissection microscope (another type of light microscope) which illuminates the sample from above, eliminating the need for a thin sample size. As the name suggests, this is normally used in dissections, and is of low magnification.
Why must the course adjustment knob be turned forward only while watching from the side?
The course adjustment knob must be turned forward only while watching from the side to ensure that the microscope's objective lens moves closer to the specimen. This allows for focusing on the specimen and achieving a clear image. Turning the knob in any other direction may result in moving the objective lens away from the specimen, leading to an out-of-focus image.
Why is it useful to turn the specimen on its side for this part of your study?
It is important to turn Êthe specimen on its side while dissecting Êbecause different organs Êof a specimen are best seen in a side view. This makes it easier Êfor study.
What is the difference between microscope and compound microscope?
A stereo microscope shows two slides side by side at the same time and is used for comparison. A compound microscope only shows one slide.
Small knob on the side of a microscope that helps you focus the microscope?
Nosepiece
Which microscope provides a right-side-up image?
The stereoscopic microscope provides a right side up image
What is the difference between stereo microscope and compound microscope?
A stereo microscope shows two slides side by side at the same time and is used for comparison. A compound microscope only shows one slide.
Why cant opaque objects be veiwed under a compound microscope?
That is certainly not true. A "compound" microscope is one that has an objective AND an ocular. Typically the front focal distance is so short that illumination through the specimen is most common. A "simple" microscope has only one magnifying lens group, not two or more. Short front focus makes lighting from the side more difficult but not impossible or even rare.
What are the large and small knobs on the side of a microscope?
The knobs on the side of a microscope are the focus knobs. The large one is the course focus, and the smaller one is the fine focus.
What part in the microscope is the most important and why?
There're two knobs at the side of a light microscope (this is just my experience, it may be different if you're using different brands of microscope or even an electron type microscope). For first focus, adjust the larger knob (also known as rough adjustment) followed by the final focus (to sharpen the image), by adjusting the smaller knob (known as fine adjustment).
What holds the specimen for viewing on an microscope?
Stage and Stage Clips The stage is a platform for the slides, which hold the specimen. The stage typically has a stage clip on either side to hold the slide firmly in place. Some microscopes have a mechanical stage, with adjustment knobs that allow for more precise positioning of slides.
