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 × 10 3 eV)(1.60 × 10 –19 J/eV)/(3.00 × 10 8 m/s) = 5.33 × 10 –23 kg·m/s. This is also the magnitude of the momentum of the electron. The kinetic energy of the
