A beam of electrons is accelerated from rest through a p.d. of 1.0 kV.
a. What is the energy (in eV) of each electron in the beam?
b. Calculate the speed, and hence the momentum (mv), of each electron.
c. Calculate the de Broglie wavelength of each electron.
d. Would you expect the beam to be significantly diffracted by a metal film in which the atoms are separated by a spacing of 0.25 × 10⁻⁹ m?
