In an x-ray diffraction experiment, the first order Bragg peak from x-rays scattering from crystal planes parallel to the surface is observed at θ = 34.0. The lattice constant (distance between atoms) is 0.347 nm. (a) (5 pts) What is the wavelength of the x-rays? (b) (5 pts) Suppose there is a set of atoms that form crystal planes that makes an angle of 45 degrees with the surface of the crystal. Using the wavelength from (a), at what angle is the first order Bragg peak relative to the surface

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: The angle of incidence has to be equal to the angle of reflection. The difference in the beam's path from a source to an observer for neighboring planes has to be equal to an integer multiple of the wavelength; that is,...
