3. The resolving power of a microscope depends on the wavelength used. To see an atom, a solution of ~ 1x10-11 m would be required. If electrons were used in an electron microscope, what minimum kinetic energy (in eV) would be required? Compare to the acceleration of the electron beam in a typical high resolution transmission electron microscope (TEM).

Light of wavelength 589 nm is used to view an object under a microscope. The objective lens of the microscope is the lens that gathers light from the object being observed and focuses the light rays in order to form an image of the object. It acts as the aperture of the system, determining its resolution. In this case, the objective lens is circular, of diameter 0.95 cm. Assuming that the resolution of the microscope depends solely on the diffractive...

RESOLUTION: This property of the compound microscope is the degree to which the detail in the specimen is retained in the magnified image. It is the ability of a microscope to distinguish two closely spaced objects as separate and distinct entities. Conventional light microscopes have a resolution of about 0.2 μm. RESOLVING POWER (d) is the closest spacing between two points at which the points can still be seen rly as separate entities. The smaller the resolving power, the smaller...

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...
