Calculating magnification:d. Muluply the power (magnification) of the evepiece by the power of the objective lensto obtain the total magnification.b. The power of the eyepiece is 10x.C. The power of each objective lens is written on it. It is usually followed by an "x", andis an integer, NOT a decimal number, e.g., "4x".d. In any sketches you make, include the total magnification under which you observedthe specimen. Always include the "x" as part of the magnification (e.g., 10x, 400x).Fill out this table:TotalName of objective Magnification Magnification ofof Ocular lenslensobjective lensmagnificationScanning lens (4x)Low power lens(10x)High power lens(40x)Oil immersion lens(100x)Check out the following interactive demo on relative cell size:https://learn.genetics.utah.edu/content/cells/scale/Based on the demo, rank the structure in order from least to greatest according to their size.Which of these could you see without a microscope?Which of these would you need to use a microscope with 1000X magnification to see?Which of these would you not be able to see with a 1000X magnification microscope?

Previous question: The field of view is the maximum area visible through the lenses of a microscope, and it is represented by a diameter. To determine the diameter of your field of view, you can place a transparent metric ruler under the low power (10X) objective of a microscope. You would focus the microscope on the scale of the ruler and measure the diameter of the field of vision in millimeters. Refer to the image taken of this preparation below. What is the approximate field of view as seen by this 10X objective. Note: This microscope has a 10X eyepiece, giving a total magnification of 100X. The image shows the 1mm is for this question. - Answer for this question was 3mm.
a. Why must you slowly turn the fine adjustment knob? b. Is natural light or is artificial light used when using the microscope?
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
Plssssss helppppp, Describe the differences you see between the three slides.
Shown below are several micrographs (images from microscopes) that were taken using different microscopy techniques. Write down what method of microscopy was used and why you thought so. Choices for microscopy techniques are: Transmitted Light Microscopy (techniques of brightfield, phase-contrast, darkfield, DIC all fall under this), Fluorescence Microscopy, Scanning Electron Microscopy, and Transmission Electron Microscopy.
Explain why resolving power is important in microscopy.
Using the microscope Answer the following questions as you work through this exercise: 1. How is the letter “e” on the slide oriented when you see it with the naked eye as you mount it on the stage (i.e., is it right side up or upside down)? 2. How is the letter “e” on the slide oriented when you see it under low or high power magnification? 3. What effect, if any, does the compound light microscope have on the orientation of the image?
3D dimensionality is a limitation of the compound microscope. Depth of field, DOF, describes dimensionality form top to bottom and can be observed with colored cross threads. Observe the crossed thread slide on low power (4x), then on medium power (10x), then on high power (40x objective magnification). Which crossed fiber is on top? How do you know?
a. When buying a microscope, what features are most important tocheck for?b. What is probably true of a $20 microscope that claims to magnify1,000×?
answer the following: instruction.match the name of the major part (listed below) with its location on the microscope, and give a very brief description of what each is used for:
a. Do you open both eyes or close one eye when viewing a specimen under a microscope? Why? Why not? b. In using a compound microscope, do you start with the low power objective (LPO) or the high power objective (HPO)? Why or Why not? c. When using 60X, do you it together with the coarse adjustment knob or fine adjustment knob? d. Why must you slowly turn the fine adjustment knob? e. Is natural light or is artificial light used when using the microscope?
