- 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 umIf the ocular lens of a microscope has 10X magnifying power, and the 40X objective lens is being used for observation, what is the total magnification for the viewed image? 10x 43x 1000x 400xComplete the following table by calculating the total magnification of the different objectives of the microscope with the given eyepieces.

LPO НРО OIO Focal length (mm) Working distance (mm) Linear magnification (X) Numerical aperture (N.A..) Features (color of the band, diameter of the opening of the lens, etc.)What is the diameter of the field of view (DFV) of a 1000x objective lens if the DFV of a 400x objective lens is 500 μ? Express your answer in mm.The FOV on low power of a microscope is measured to be 4.5mm. Using the chart below and the above listed formulas calculate: FOvx = FOvlow X Maglow Magx S.S. = FOvx # times the specimen fits across the FOv Total Mag = Ocular lens x objective lens a) What is the FOV on High Power? (Magnification on High power is 40x) Can you please include the units too. asap please.
- These cells are being viewed under high power. Use the length of just one cell to estimate the number of cells that can fit into the FOV. Scanning power objective = 5X; Low power objective = 40X; High power objective = 100X; Eyepiece = 10X; Low power field of view (FOV) = 1.5 mmDifferentiate 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 does this statement mean: “Your microscope is parfocal”? What is the significance of condenser lens? Multiple choice question: The most useful adjustment for increasing image contrast in low power magnification is _______ Closing down the diaphragm Closing one…Using the scanning (4x) objective and the metric ruler, record the number of millimeters you see along with the letter “e.” Your value: 2 millimeters Convert the figure you attained to micrometers (1 millimeter = 1,000 micrometers). This is the diameter of the field of view for the low-power objective (LPD). The field of view is the circular field you see when you look through the oculars. The field of view changes at different magnifications. Your value (LPD): 2,000 micrometers -please help me with the problem in the picture.
- When trying to focus an object on the microscope, you always begin with the ________________ objective lens and use __________________ adjustment knob to bring the object in focus. Once object is focused, high power objective lens can be used to magnify the object, and only use the ___________________ adjustment knob to focus at this point. a scanning; coarse; fine b low power; coarse; fine c low power; fine; coarse d scanning, fine; coarseIf a specimen is being viewed under a 40x objective, and the microscope has a 10x ocular lens, what is the total magnification? 1x 4x 10x 100x 400xUsing 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?
