For crystal diffraction experiments, wavelengths on the order of
0.220 nm are often appropriate. A) Find the energy in electron
volts for a particle with this wavelength if the particle is a
photon. B) Find the energy in electron volts for a particle with
this wavelength if the particle is an electron. C) Find the energy
in electron volts for a particle with this wavelength if the
particle is an alpha particle.
