Step by step
Solved in 3 steps
- 1. What does moving the coarse focus and fine focus do? Why is it important to remember the difference between coarse and fine focus? 2. What is the resolution of a microscope? How is resolution affected byadjusting the light, coarse and fine focus? please answer on ur own words, do not copy from google or i will downvote1. Differentiate the compound light microscope from the dissecting microscope in terms of: *image produced *magnification *type of specimen examined 2. Write down the principles of the following: *electron microscopy *scanning tunneling microscopy *atomic force microscopyShown below are several micrographs (images from microscopes) that were taken using different microscopy techniques. Write down what method of microscopy was used and why you thought so. Choices for microscopy techniques are: Transmitted Light Microscopy (techniques of brightfield, phase-contrast, darkfield, DIC all fall under this), Fluorescence Microscopy, Scanning Electron Microscopy, and Transmission Electron Microscopy.
- 1. Discuss the basic/proper setup of Microscopy? (write your answer below)Describe 3 simple ways of preparing microscope slides for light microscopyUsing 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?
- 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 centerMicroscope slides: Consider commercially prepared slides and wet-mount slides. two similarities two DifferencesWhat is “parfocal” and why is it important in microscopy?
- PARTS OF THE MICROSCOPE. Match Column A with Columns B and C. Example: 1). A, CDescribe the microscope in 2-3 sentences1. In microscopy, what could be the possible reason why we cannot completely resolve the specimen under the Oil Immersion Objective (OIO) when, in fact, it was taught that the OIO has a resolving poewer? 2. When using the OIO, we can only focus on one group or parts at a time. (that is, the other parts are blurred) Whys is it so?
