For x rays with wavelength 0.0300 nm, the m = 1 intensitymaximum for a crystal occurs when the angle u is35.8. At what angle u does the m = 1 maximum occur when a beam of4.50 keV electrons is used instead? Assume that the electrons also scatterfrom the atoms in the surface plane of this same crystal.
