Degree of scattering in transmission electron microscope is a function of |
| A. | wavelength of electron beam used |
| B. | number of atoms that lie in the electron path |
| C. | number and mass of atoms that lie in the electron path |
| D. | mass of atoms that lie in the electron path |
| Answer» C. number and mass of atoms that lie in the electron path | |
| Explanation: in a transmission electron microscope, contrast results from the differential scattering of electrons by the specimen, the degree of scattering being a function of the number and mass of atoms that lie in the electron path. | |
