Consider the following The two figures below display a source of electrons. This source sends electrons with deBrosclie wavelength to a surface with two slits. The positions of those electrons passing through the slits are recorded by a moveable detector. Three groups of measurements are made for each figure. First: The right slit is closed. The detector records and plots the graph I1. Second: The left slit is closed. The detector records and plots the graph IR. Third: Both slits are open and the detector records the graph I a) 3 Pts For the left figure, The slit opening L tions for the electron many electrons are sent but only one electron is waves to produce an from the electron source. needed to form the inter- interference pattern ference pattern. are For-the-right-figure, Theslitopening L but I particles, never waves. for the electron waves many electrons are sub- to produce a particle- jected to Compton scatter- like pattern are 3Pr The electrons are always ing and are no longer co- herent H.

Explanation / Answer

For figure (a) , A is correct because to have a intensity distribution we need more than 1 electrons

For figure (b), A is correct, because compton scattering changes electron momentum due to uncertainty principle and the interference pattern is lost.
