(a) 6.2 keV (b) 38 eV (c) 5.2 meV
7. For crystal diffraction experiments, wavelengths on the order of 0.20 nm are often appropriate, since this is the approximate spacing between atoms in a solid. Find the energy in eV for a particle with this wavelength if the particle is (a) a photon, (b) an electron, (c) an alpha particle (mc? = 3727 MeV).
