- Complete the following table by calculating the total magnification of the different objectives of the microscope with the given eyepieces. OBJECTIVES OCULAR Designation Magnification Focal Length Numerical Aperture (NA) Final magnification with: 10x 15x 25x Scanner 4x 46mm 0.10 LPO 10x 16mm 0.25 HPO 40x 4mm 0.55 OIO 100x 1.8mm 1.30Using 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.What are the underlying physical principles of paper chromatography? What is spectrophotometry, the essence of it?
- What are the differences between scanner, low power objective, high power objective and oil immersion objective? Introduce the terms stated above and explain comprehensively.What information can be obtained from the slides prepared by wet mount and hanging drop technique for microscopic observation? Give at least three (3) information. What are the limitations of each method. (Provide 2 limitations)Define each of the following terms: A) What is resolution and how is resolution related to the wavelength of light used to illuminate the sample? B) What is the magnification of the specimen if you are using a 40x objective and a 10x eyepiece? C) How is the numerical aperture (NA) of a lens related to its ability to gather light from a specimen?
- 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?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 mmIntroduce and explain comprehensively the process of calculating the final magnification of specimens using a compound microscope. What is scanning objective and why it should be located at the beginning of the process?
