Unformatted text preview: Explain your answer. (2) Yes. Mag = (10x) x (100x) = 1,000x. Since the bacteria are 1.0 um diameter they can be seen at this mag. And, since the microscope resolution maximum is 264 nm (i.e., less than 500 nm) they can be detected as two separate entities. 3. What two light microscopy procedures or techniques could you use to improve the visibility of the cells and bacteria specimen described above? (2) a) Stain the specimen with chemical dyes to create contrast. b) Use phase-contrast or DIC microscopy to achieve contrast. 4. What is meant by the term “ empty magnification ”? (2) Magnification that gives a larger image without improving the resolution. . ( Magnification beyond the resolving power of a scope). Page 3 Name _______________________________ Demo...
