- Why is it sometimes difficult to attain both good resolution and good contrast at the same time for a sample that is being observed on the microscope stage? Please give a thorough response,True or False: Ultrathin sections are used for light microscopy but are to thin to be stable under an electron mocroscope X-ray beam.The resolution of a microscope could be increased by raising the condenser to its highest point. True or False
- True or false : each objective of a phase contrast microscope contains a phase plate. phase contrast microscopy relies on the condenser to increase the contrast of an image. in brightfield microscopy, closing the condenser aperture will decrease the contrast of the speciment. stained cell speciments are best viewed by phase contrast microscopy.The diffraction limit is an unbeatable barrier limiting the effective resolution of light microscopy due to the inherent wavelength of light.True or FalseIn light microscopy, when magnification is increased, the lens focuses closer to the sample. This makes the user more likely to ram the sample into the lens. Why is it common for the lens to focus closer to the sample at higher magnifications? What can be done to mitigate this risk?
- Of the four major types of microscopes, give an example of a scenario in which each would be the ideal choice for visualizing a sample. Stereo (Dissecting) Compound Confocal ElectronWhy would specimens viewed with a compound microscope be thin and/or chemically cleared?Explain in detail simple and differential staining and also improving and adjusting contrast in light microscopy.
- Explain 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?The above photograph (IMAGE ATTACHED) of a cheek smear was obtained using the high-power objective of a compound microscope. What is the size of the circled cheek cell in millimeters AND nanometers?True or False: The coarse and fine adjustments are partof the microscope’s mechanical system_________________.
