- when viewing an organism under the 40x objective lens, you estimate that 6 organims could fit across the DFV if they were laid end to end and 20 could fit if stacked side by side. What is the length and width of this organism in micra?You are asked to calibrate the ocular micrometer for the 4x objective using the stage micrometer. You observe 32 stage micrometer units line up with 15 ocular micrometer units. What is the value for each division of the ocular micrometer for this objective? (Round to the 1 decimal place)The third micrograph is at the lowest magnification. Identify A (name of the cells; blank 1). Identify B (name of the structures arrows point to; blank 2) - Identify C (name of the structures arrows point to; blank 3) High mag low mag high mag Blank # 1 Blank # 2 Blank # 3
- How many coccus cells (0.0005 mm in diameter) could fit across the entire FOV of the 100x objective lens (assuming the DFOV of the 100x lens is 180 μm?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 mmThe Leica microscope that we will be using for histology lab has four different objective lenses and an ocular lens. When you are looking at blood cells through the ocular lens and using the 10x objective, the total magnification of the blood cells will be: 1) 400X 2) 10X 3) 100X 4) 20X
- how would this be drawn if it was inside the image?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.A student was observing a filament of blue green bacteria under low power (60X). The diameter of the field is 2.4 mm. At this magnification, the student was able to count 40 cells in a row across the middle of the field of view. a. What would be the average length of each cell? b. If the student switched to high power (600X), about how many cells would be seen
- The field of view (FOV) is the entire circular image we see when looking into the eyepiece. The diameter of the FOV gets smaller as we increase magnification. It can be measured by using a stage micrometer like a ruler, measuring from edge to edge. Notice that the stage micrometer is 1000 microns (µm) in length, and the field of view under the lowest magnification is 5000 µm. Describe how we measure it?If you are using a microscope and a specimen takes up 1/4 of the field of vview at 1000X, what is the diameter?The actual length of a cell is 50µm. When projected on the big screen in the class, the same cell is 2m long. What is the magnification factor of the cell on the screen? 1 000x 4 000x 10 000x 40 000x 100 000x 400 000x
