Rotate the condenser focus knob to bring the condenser down to the bottom and partially open the iris diaphragm.c. Rotate the coarse adjustment knob to focus the image. Move it as far as it will go without touching the slide.d. When coarse…

A. Purpose: Figure 1 B. Materials: Microscope Magazine Slides and cover slips Paper towels Pipette Scissors C. Procedure: 1. Careful carry a microscope to your lab area. Make sure to hold it with one hand under the base and one hand on the arm as shown in Figure 1. 2. Plug the microscope in and turn it on. Take a moment to look at all the parts of the microscope. Then look at your ocular lens. What is the magnification of the ocular lens (eye piece)? Figure 2 3. Fill in the chart to show the total magnification for each objective lens. Magnification of Ocular Lens Magnification of Objective Lens Objective Lens Total Magnification Low Power Medium Power High Power

a.  Why must you slowly turn the fine adjustment knob? b.  Is natural light or is artificial light used when using the microscope?

Give a particular use/uses of the following types of a microscope: 1. Research microscope 2. Stereomicroscope 3. Student microscope 4. Projection microscope

Can you help me to fill in the function of each, please

Please answer the following questions (Question 1 AND 2) about compound microscopes. After clicking the objective into position, which adjustment knob(s) can you use to safely refocus the image? You may need to adjust the light intensity to better see the specimen. Indicate two ways in which you can change the light intensity?

9:06 LTE 4) Answer true or false to each of the following statements. On high power, you should use the coarse adjustment knob. The diaphragm determines how much light shines on the specimen. The low power objective has a greater magnification than the scanning objective. The fine focus knob visibly moves the stage up and down. Images viewed in the microscope will appear upside down. If a slide is thick, only parts of the specimen may come into focus. The type of microscope you are using is a scanning microscope. For viewing, microscope slides should be placed on the objective. In order to switch from low to high power, you must rotate the revolving nosepiece. The total magnification of a microscope is determined by adding the ocular lens power to the objective lens power.

Answer the following questions: Why are most cells so small? Why cell size is limited? List two instances when the coarse adjustment knob is never used Why is immersion oil used with the 100X objective? List two common problems associated with using the microscope and how you would  go about solving it. When should the lenses be cleaned?  What is the correct way to clean them?

Previous question: For example, you can estimate the field of view diameter at 400x total magnification using the measured diameter at 100x total magnification. The magnification is 4 times greater so the field of view will be 4 times smaller. What is the field of view under the 40X objective of the microscope. - The Answer I got for this question was 3/4mm.

Write T (True) or F (False) for the following statements. 1. The objective lens is the one nearest to the observer's eye. 2. Only special lens paper should be used to clean the objectives, oculars, and the condenser of the microscope. 3. The working distance is the distance between the specimen and the objective lens. _4. Magnifying a blurred image generally reveals further details. 5. When a microscope is parfocal, you should not have to use the coarse adjustment at higher magnification. _6. The total magnification of the object seen at high dry power is approximately 40X. 7. Immersion oil can be used to increase resolution of all the objective lenses in a brightfield microscope. _8. Always be sure to oil your microscope lenses before returning the instrument to its designated space. 9. Animals will not survive without mitochondria because they will not be able to make ATP. 10. The use of normal saline solution (NSS) in viewing cheek cells is to prevent lysis or crenation of cells.
