In electron diffraction, an electron moving at speed v

[ts19998]

In electron diffraction, an electron moving at speed v << c acts like
 a. a particle with momentum mv.
  b. a particle with position coordinate v/t.
  c. a wave with wavelength v/t.
  d. a wave with wavelength h/mv.
  e. both a particle with position coordinate v/t and a wave with wavelength v/t.

Question 2

A quantum particle
 a. can be localized in space. b. can be represented by an infinitely long wave having a single frequency.
  c. can be represented by a wave packet.
  d. travels at the phase speed of the infinitely long wave having the highest frequency.
  e. has the highest probability of being present in those regions of space where its component waves interfere destructively.
