- What is the highest magnification of the following microscopes?Bright fieldDark fieldPhase-contrastFluorescenceConfocalScanning EMTransmission EMScanned-ProbeWhy don’t most light microscopes use 303 ocular lenses for greater magnification?What major advantage does phase-contrast microscopy haveover staining?
- What is the advantage of phase-contrast microscopyover bright-field microscopy?Simple staining is often necessary to improve contrast in which microscope? fluorescence microscope O clectron microscope O darkfield microscope compound light microscope O phase-contrast microscopeExplain when to use bright-field, phase-contrast, dark-field, fluorescence, transmission electron, and scanning electron microscopy for a given situation. What is an example of this situation?
- How can a UV-Vis spectrophotometer be applicable in determining the absorbance/concentration of a colorless sample? Please answer in detail and clearly. Thank you so much!For a microscope that has an objective lens magnification of 100X and an ocular lens magnification of 5X, calculate the total magnification. 500X O 1000X O 50X O 100X O No listed answer is correct.The magnification possible with any type of microscope is an important property, but its resolution, the ability to distinguish between two very closely apposed objects, is even more critical. Describe why the resolving power of a microscope is more important for seeing finer details than its magnification.
- Explain the difference in the working principles of Dark-field and Light-field microscopes using pKk contrast.If the total magnification of a microscope is 700X and the ocular lens magnifies by a factor of 10x, what is the magnification of the objective lens that was used? Paragraph BIUHow does the compound microscope achieve magnification? resolution? Cite your reference/s if possible.
