If an electron is accelerated by a potential difference of $1.0 \times 10^4 \ V$,calculate its kinetic energy,frequency,and wavelength.

• A
  $KE = 1.602 \times 10^{-15} \ J, \nu = 2.418 \times 10^{18} \ Hz, \lambda = 1.227 \times 10^{-11} \ m$
• B
  $KE = 1.602 \times 10^{-16} \ J, \nu = 5.933 \times 10^{17} \ Hz, \lambda = 1.227 \times 10^{-10} \ m$
• C
  $KE = 1.602 \times 10^{-15} \ J, \nu = 5.933 \times 10^{17} \ Hz, \lambda = 1.227 \times 10^{-11} \ m$
• D
  $KE = 1.602 \times 10^{-14} \ J, \nu = 2.418 \times 10^{17} \ Hz, \lambda = 1.227 \times 10^{-12} \ m$
