The picture below shows electron diffraction patterns of electrons (as
4 point
matter waves) that diffracted through two identical metal surfaces; all other diffraction variables were controlled between the two samples,
except for the following: one of the two beams of electrons had a uniform
higher kinetic energy per electron, and the other beam had a uniform Iower kinetic energy per electron. Which beam of electrons had the greater uniform kinetic energy per electron? *
diffraction of electron beam off the same surface
The electron beam that produced the electron diffraction pattern on the left
The electron beam that produced the electron diffraction pattern on the right
The electron beam kinetic energy is unrelated to the diffraction pattern
It is not possible to infer from these diffraction pictures
The higher the frequency of a matter wave,*
4 point
the less it will diffract through a given opening through which it can diffract
the more it will diffract through a given opening through which it can diffract
the greater its matter wavelength
the more likely it will reflect
