Consider a beam of mono-energetic electrons incident on apowder of crystal fragments, each with theatoms arranged in a cubic array with d being the distance between nearestneighbors.
(a)if the transmitted electrons form a diffraction pattern, describe what will be observed.
(b) what is the lowest energy electrons can have, in order to produce any diffraction pattern.(c) what happens if the electron energy is lower than what you have found in part (b).
