54. The same resolution requires the same wavelength, and since the wavelength and particle momentum are related by p = h/λ, we see that the same particle momentum is required. The momentum of a 100 keV photon is p = E/c= (100 ×103eV)(1.60 ×10–19J/eV)/(3.00 ×108m/s) = 5.33 ×10–23kg·m/s. This is also the magnitude of the momentum of the electron. The kinetic energy of the
