- During observation under the microscope, the number of optical planes that are in focus simultaneously define: practicg The Working Distance The Field of View O The Depth of FieldPrevious 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.Which of the following statements are true in the context of the microscope's field of view? I. It is the observable area within a circular space as defined by the lenses II. FOV is the smallest on the lowest power objective III. FOV is the maximum area visible through the microscope eyepiece IV. When you switch to a higher power, the field of zooms out towards the center
- Explain why resolving power is important in microscopy.a) Describe the technique Of Atomic Force Microscopy under the following headings: (i) Basic principle of AFM and overview of operations (ii) Modes of A FMDifferentiate between the limit of resolution of the typical light microscope and that of the unaided human eyes the relationship between the depth of field and magnification is that When magnification increases, the depth of field decreases. Name two procedures (steps) you should do to achieve the maximum resolution when using the oil immersion lens State the relationship between the working distance of an objective lens and its magnification power “The coarse focus knob can be used to adjust the focus when using any of the objective lenses”. Is this statement true or false? If it is false, please correct it. When using the oil immersion lens but you cannot focus, what should you should not do? And what you should do?

What is an example of this situation?Define field of view and working distance as it relates to working with a microscope.
- You are in charge of buying new microscopes for your company, and you have been comparing different types of microscopes. One important property for microscopy is the resolution, which measures the ability to distinguish two small objects that are close together. Rank the following list of microscopes from lowest to highest resolution. Microscope List (5 items) (Drag and drop into the appropriate area) Transmission electron microscope (uses high energy electron beam) X-ray microscope (uses x-ray absorption to image sample, range 0.01-10 nm) Confocal fluorescence microscope (uses a blue laser as a light source, 488 nm) Level of Resolution 2 LowestWhich of the following is true about the relationship between depth of field and magnification? There is no relationship. When magnification increases, depth of field decreases. When magnification increases, depth of field increases. Stereomicroscopes offer a lesser depth of field than compound microscopes. The depth of field of a microscope determines how much magnification it can achieve.Calculate the diameter of the field of view for each total magnification on your microscope in millimeters (mm) and then convert this value to micrometers (um): 4,500 um Scanning (40X): 1.8 mm x 100X/40X = 5 mm = %3D Low power (100X): FOV diameter = 1.8 mm = 1,800 um 1.8 mm x 100X/400X = 0.45 mm =450 um 180 um High power (400X): 1.8 mm x 100X/1000x = 28 mm = Oil immersion (1000X): %3D Draw and estimate the length of a single Euglena (high power) and Paramecium (low power): Paramecium Euglena total magnification total magnification FOV diam. um FOV diam. um length um length um
