When an x-ray beam is scattered off the planes of a crystal, the
scattered beam creates an interference pattern. This phenomenon is
called Bragg scattering. For an observer to measure an
interference maximum, two conditions have to be satisfied:
a). An x-ray beam with wavelength 0.120 nm is directed at a
crystal. As the angle of incidence increases, you observe the first
strong interference maximum at an angle 23.0 ∘. What is the spacing
d between the planes of the...
